- *
- * Responder being granted:
- * ------------------------
- *
- * - Touch starts, moves, and scrolls can cause an ID to become the responder.
- * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
- *   the "appropriate place".
- * - If nothing is currently the responder, the "appropriate place" is the
- *   initiating event's `targetID`.
- * - If something *is* already the responder, the "appropriate place" is the
- *   first common ancestor of the event target and the current `responderInst`.
- * - Some negotiation happens: See the timing diagram below.
- * - Scrolled views automatically become responder. The reasoning is that a
- *   platform scroll view that isn't built on top of the responder system has
- *   began scrolling, and the active responder must now be notified that the
- *   interaction is no longer locked to it - the system has taken over.
- *
- * - Responder being released:
- *   As soon as no more touches that *started* inside of descendants of the
- *   *current* responderInst, an `onResponderRelease` event is dispatched to the
- *   current responder, and the responder lock is released.
- *
- * TODO:
- * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
- *   determines if the responder lock should remain.
- * - If a view shouldn't "remain" the responder, any active touches should by
- *   default be considered "dead" and do not influence future negotiations or
- *   bubble paths. It should be as if those touches do not exist.
- * -- For multitouch: Usually a translate-z will choose to "remain" responder
- *  after one out of many touches ended. For translate-y, usually the view

-  // However, we want to avoid allocating extra fibers for every placeholder.
-  // They're only necessary when the children time out, because that's the

- *
- * Responder System:
- * ----------------
- *
- * - A global, solitary "interaction lock" on a view.
- * - If a node becomes the responder, it should convey visual feedback
- *   immediately to indicate so, either by highlighting or moving accordingly.
- * - To be the responder means, that touches are exclusively important to that
- *   responder view, and no other view.
- * - While touches are still occurring, the responder lock can be transferred to
- *   a new view, but only to increasingly "higher" views (meaning ancestors of
- *   the current responder).
- *
- * Responder being granted:
- * ------------------------
- *
- * - Touch starts, moves, and scrolls can cause an ID to become the responder.
- * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
- *   the "appropriate place".
- * - If nothing is currently the responder, the "appropriate place" is the
- *   initiating event's `targetID`.
- * - If something *is* already the responder, the "appropriate place" is the
- *   first common ancestor of the event target and the current `responderInst`.
- * - Some negotiation happens: See the timing diagram below.
- * - Scrolled views automatically become responder. The reasoning is that a
- *   platform scroll view that isn't built on top of the responder system has
- *   began scrolling, and the active responder must now be notified that the
- *   interaction is no longer locked to it - the system has taken over.
- *
- * - Responder being released:
- *   As soon as no more touches that *started* inside of descendants of the
- *   *current* responderInst, an `onResponderRelease` event is dispatched to the
- *   current responder, and the responder lock is released.
- *
- * TODO:
- * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
- *   determines if the responder lock should remain.
- * - If a view shouldn't "remain" the responder, any active touches should by
- *   default be considered "dead" and do not influence future negotiations or
- *   bubble paths. It should be as if those touches do not exist.
- * -- For multitouch: Usually a translate-z will choose to "remain" responder
- *  after one out of many touches ended. For translate-y, usually the view
- *  doesn't wish to "remain" responder after one of many touches end.
- * - Consider building this on top of a `stopPropagation` model similar to
- *   `W3C` events.
- * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
- *   not `onResponderTerminationRequest` returns `true` or `false`.
- *
+ * Return the lowest common ancestor of A and B, or null if they are in
+ * different trees.

+ *
+ * Responder System:
+ * ----------------
+ *
+ * - A global, solitary "interaction lock" on a view.
+ * - If a node becomes the responder, it should convey visual feedback
+ *   immediately to indicate so, either by highlighting or moving accordingly.
+ * - To be the responder means, that touches are exclusively important to that
+ *   responder view, and no other view.
+ * - While touches are still occurring, the responder lock can be transferred to
+ *   a new view, but only to increasingly "higher" views (meaning ancestors of
+ *   the current responder).
+ *
+ * Responder being granted:
+ * ------------------------
+ *
+ * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+ * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+ *   the "appropriate place".
+ * - If nothing is currently the responder, the "appropriate place" is the
+ *   initiating event's `targetID`.
+ * - If something *is* already the responder, the "appropriate place" is the
+ *   first common ancestor of the event target and the current `responderInst`.
+ * - Some negotiation happens: See the timing diagram below.
+ * - Scrolled views automatically become responder. The reasoning is that a
+ *   platform scroll view that isn't built on top of the responder system has
+ *   began scrolling, and the active responder must now be notified that the
+ *   interaction is no longer locked to it - the system has taken over.
+ *
+ * - Responder being released:
+ *   As soon as no more touches that *started* inside of descendants of the
+ *   *current* responderInst, an `onResponderRelease` event is dispatched to the
+ *   current responder, and the responder lock is released.
+ *
+ * TODO:
+ * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+ *   determines if the responder lock should remain.
+ * - If a view shouldn't "remain" the responder, any active touches should by
+ *   default be considered "dead" and do not influence future negotiations or
+ *   bubble paths. It should be as if those touches do not exist.
+ * -- For multitouch: Usually a translate-z will choose to "remain" responder
+ *  after one out of many touches ended. For translate-y, usually the view
+ *  doesn't wish to "remain" responder after one of many touches end.
+ * - Consider building this on top of a `stopPropagation` model similar to
+ *   `W3C` events.
+ * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+ *   not `onResponderTerminationRequest` returns `true` or `false`.

-  // The two sets of children are siblings in the host environment, but

-  // So we store them using two fragment fibers.
+  // First, Legacy Mode has different semantics for backwards compatibility. The
+  // primary tree will commit in an inconsistent state, so when we do the
+  // second pass to render the fallback, we do some exceedingly, uh, clever
+  // hacks to make that not totally break. Like transferring effects and
+  // deletions from hidden tree. In Concurrent Mode, it's much simpler,
+  // because we bailout on the primary tree completely and leave it in its old
+  // state, no effects. Same as what we do for Offscreen (except that
+  // Offscreen doesn't have the first render pass).
   //
-  // However, we want to avoid allocating extra fibers for every placeholder.
-  // They're only necessary when the children time out, because that's the
-  // only time when both sets are mounted.
+  // Second is hydration. During hydration, the Suspense fiber has a slightly
+  // different layout, where the child points to a dehydrated fragment, which
+  // contains the DOM rendered by the server.
   //
-  // So, the extra fragment fibers are only used if the children time out.
-  // Otherwise, we render the primary children directly. This requires some
-  // custom reconciliation logic to preserve the state of the primary
-  // children. It's essentially a very basic form of re-parenting.
+  // Third, even if you set all that aside, Suspense is like error boundaries in
+  // that we first we try to render one tree, and if that fails, we render again

-        //
-        // Restarting too aggressively is also not good because it starves out any
-        // intermediate loading state. So we use heuristics to determine when.

-        // If nothing threw a Promise or all the same fallbacks are already showing,

-        // that we can show the initial loading state as quickly as possible.
-        //
-        // If we hit a "Delayed" case, such as when we'd switch from content back into
-        // a fallback, then we should always suspend/restart. SuspenseConfig applies to
-        // this case. If none is defined, JND is used instead.

-        // then we suspend/restart for 500ms since the last time we showed a fallback

-        // consistent train of commits. This also gives us an opportunity to restart to
-        // get to the completed state slightly earlier.
