This is needed because this function is now potentially called on every mouse-move, and we don't want to restart the timer.

This fixes the case of press -> exit -> enter
Previously we would re-show the tooltip.

Re-show the tooltip on mouse-move (but no buttons pressed).

Not sure why this was needed, and in any case it's buggy - you're supposed to put the while inside the awaitPointerEventScope.

Not sure why there was a need for a custom implementation here.

Why do we need Initial instead of the main pass here?

I don't know, but it was in the code already, so I decided not to change it just in case.
The tooltip is currently hidden when the
TooltipAreais pressed, and it remains hidden until mouse exit and re-enter.This is a problem for widgets that have more than one mouse interaction per hover session, e.g. a text field.
