Major Changes

• b6ea4b5: Breaking: Fixed a long-standing bug where onPostActivate() would be called before the initial focus node was focused and the trap was fully activated. (#​1747)
  • By default (and for many years now), a trap delays setting focus to the initial focus node to the next frame (setTimeout(0)) but wasn't delaying calling onPostActivate() until after that delay.
  • With the new isolateSubtrees='aria-hidden' option, the currently-focused node's container (a non-subtree being "disabled") would get hidden before the delay was up, resulting in Chrome preventing the effect of aria-hidden on that subtree with a warning in the console due to the container being hidden still containing focus (e.g. the "activate trap" button).
  • With the fix, subtree isolation and the call to onPostActivate() await the initial focus delay (if there is one, which is default behavior; remove it with delayInitialFocus=false) before being applied/called.
  • This may cause tests to fail, requiring the addition of slight delays before testing a given state (e.g. await waitFor(() => expect(initialFocusNode).toBeFocused()).
  • It may also disrupt current assumptions about the state of the initial focus node in code that runs in your onPostActivate() handler (prior to this change, that node would not be focused yet; after this change, it will be focused).
