A small panel of *content* hung off a control.

Open one and press Tab — the panel is a dialog, and focus is inside it.
That link is why this is a popover and not a tooltip. A tooltip describes its anchor — a few words, no
focus, reaching a screen reader through
aria-describedby. Anything a person has to reach belongs here,
where focus goes in and comes back. A “tooltip” holding a link is content a keyboard user can see and cannot get to,
and it is the commonest accessibility defect in commercial component suites.
