What happened?

1. When Talkback is enabled Modal is not focused when presented
2. Elements below the Modal are accessible.
3. When dismissing modal, elements are no longer accessible/focusable (no green marker around them and no announcements)

There was already an issue in v4 #1641 but this issue still persists.

In general the accessibility behavior is questionable. Why is the backdrop accessible? Why is each element accessible. Handle, Container, Background. Content elements are not accessible seperatly.

Reproduction steps

1. When Talkback is enabled Modal is not focused when presented
2. Elements below the Modal are accessible
3. When dismissing modal, elements are no longer accessible/focusable (no green marker around them and no announcements)

Describe what you expected to happen:

1. When Talkback is enabled, if user opens Modal, it should get focus automatically
2. Elements below the Modal should not be accessible by default (some prop needed maybe)
3. After dismissing Modal, elements that were below it should be accessible/focusable again

++ Would love a resolution for this as well

Made a patch-package to fix this issue if anyone's interested in a quick fix:

• Added importantForAccessibility prop to BottomSheet, BottomSheetModal, BottomSheetBackdrop, BottomSheetBackground and BottomSheetContainer
• Added logic to the BottomSheetModalProvider to disable accessibility for app child elements while giving accessibility to the modal content.

Based on the suggestions in #687
Manually focusing the modal does not seem to be necessary once the rest of the content is non-accessible, as the screen reader will jump to the first available element.

I would suggest creating a custom handle for closing the modal that you can make accessible while hiding the backdrop like this:
