Consider modal/dialog for Link Control popover when used

[MaggieCabrera]

While working on the component's tests, we found that the popover doesn't have an accessible name. Also the focus is trapped inside the popover.

Should we be using a modal/dialog instead?

I actually don't know. I'd have to defer to folks with specific expertise in this area as it seems quite difficult to know what's best.

Do we have any components that fulfil the role? Surely our Popover is accessible and provides the correct role .etc?

If you implement focus trap, it is probably best to implement modal while you are at it. Screen readers on Windows cannot navigate out of modals via browse/virtual mode but they can navigate away from popovers, non-modals. I define modals as the <modal tag or role="modal". The Modal in wordpress/components should be fine.
