Unable to move TalkBack cursor on Modal component

[warsawgentleman]

Provide a general summary of the issue here

When Modal is opened via TalkBack I am unable to change cursor position by swiping left or right. The cursor always comes back to the first focusable element. The flow works perfectly on VoiceOver (macOS).

🤔 Expected Behavior?

I should be able to navigate the elements inside Modal by swiping left or right.

😯 Current Behavior

TalkBack cursor is blocked on the first element.

Thanks for reporting this, verified locally, digging to see when it started happening.

Looks to be something in our FocusScope:

react-spectrum/packages/@react-aria/focus/src/FocusScope.tsx

Lines 383 to 385 in 7eae25e

	raf.current = requestAnimationFrame(() => {
	// Use document.activeElement instead of e.relatedTarget so we can tell if user clicked into iframe
	if (ownerDocument.activeElement && shouldContainFocus(scopeRef) && !isElementInChildScope(ownerDocument.activeElement, scopeRef)) {

where the activeElement is now returning the document body after the RAF instead of the newly focused input element after the swipe operation. Replacing this with e.relatedTarget seems to work just fine, I can't seem to reproduce the original issue in Firefox even with the updated change

The fix above actually breaks another use case of ours since we still do want to coerce focus back to the Modal if focus is genuinely lost to the body but there isn't a great to differentiate that any longer for Talkback it seems. I've filed a bug against Chrome via https://issuetracker.google.com/issues/384844019 to see if they can shed any light as to what may have changed as of late, currently digging to see if there are any alternative paths here.
