Actual Behavior

Error message appears in debugger console when alert is closed:

Blocked aria-hidden on an element because its descendant retained focus. The focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.
Element with focus: button
Ancestor with aria-hidden:

Expected Behavior

No error message

What's weird is that if I change the Calcite version, the problem is usually not repeatable, including if I go back to version 2.13.2. (I was trying to answer the regression? question.)

Reproduction Version

2.13.2
