Hi,

Google Maps JS API team is blocked by this bug.

Please consider the following demo: https://codesandbox.io/s/headless-sunset-7fted.

There are 2 `div` elements with `tabindex`, `role` and `aria-label` attributes defined. Voice Over on iOS devices (Safari and Chrome) skips these elements and navigates to child elements (either focusable or non-focusable) when using gestures (swipe left and right) to navigate through elements on a page.

We use `role="group"` attribute. W3 says that `group (role)` attribute is "a set of user interface objects which are not intended to be included in a page summary or table of contents by assistive technologies.", so we tried `role="region"` attribute and according to W3 "Assistive technologies *SHOULD* enable users to quickly navigate to elements with role region".

Please note, that Voice Over on MacOS devices does recognize elements with `role="region"` and `role="group"` when navigating using Tab/Shift-Tab and VO + Left arrow/VO + Right arrow keys.

Please let us know if more details are needed.
