[Popover] - allow its sparing usage for interactive content

[dgdavid]

Is this a new component or an extension of an existing one?

And extension/adjustment of Popover

Describe the feature

Allow interactive content for using it in scenarios where other components such as Modal, Menu, or Dropdown, don’t quite fit the use case.

As an example, see the screenshots below of rough prototypes for an interface that allows users quick access to available Wi-Fi networks and keyboard layout from a top toolbar.

One concern I have is that the Popover component internally uses the aria-describedby attribute, which I believe makes the interactive content inaccessible. From my limited understanding of accessibility, and after reviewing MDN's documentation, it seems that using aria-details might help.

The aria-describedby property is appropriate when the associated content contains plain text. If the content is extensive, contains useful semantics, or has a complex structure requiring user navigation, use aria-details instead. aria-details allows assistive technology users to visit the associated structured content and provides additional navigation commands, making it easier to understand the structure, or experience the information in smaller pieces.
