Hovering the invoker confers full interest
As mentioned on the explainer PR conversation, here:
https://github.com/openui/open-ui/pull/1213#discussion_r2082158087
If the user keyboard-focuses an invoker which shows a target
popover in "partial interest" mode, subsequently mouse-hovering
that invoker should automatically upgrade to "full interest".
