Accessibility: Content in BottomSheet is hidden from screen readers

[fymmot]

There is an accessibility problem with the current implementation affecting visually impaired screen reader users.

When the bottom sheet is expanded, the attribute aria-hidden=true is set on the container element. This effectively hides everything from the screen reader, making it inaccessible.

How to reproduce

• Go to the Fullscreen example (https://manufont.github.io/react-swipeable-bottom-sheet/fullscreen.html )
• Start a screen reader, e.g. VoiceOver
• Navigate to the "Open" button and activate it

Expected behavior

• The bottom sheet is expanded and the screen reader will start reading its content.

Actual behavior

• The bottom sheet is expanded
• The screen reader cannot find any content.
