Comment (by harshdeepgill):

 Hi @joedolson , thanks for reviewing this ticket.

 As far as I can see Popovers were created with accessibility in mind, with
 a few accessibility features included out-of-box:

 * Any element can become a popover, which carries over element semantics
 to the #top-layer as well.
 * When popover elements are open, they become the next focusable element
 in the tabindex.
 * Users can close popovers by pressing the Esc key on the keyboard, as
 well as clicking outside the popover to dismiss.

 Please let me know if I am missing something.
