Close a persistent rich tooltip on a second press of its trigger

The bubble is a popover="auto" and the trigger is outside it, so the press
on the trigger light-dismissed the open bubble and the click that followed
opened it again: a second press never closed it, in any engine. Found by
the new exit test. A close the browser made within 250ms is now taken for
that press, as menu.js's REOPEN_GUARD_MS does, timed from beforetoggle
because toggle is queued past the click; the morph test waits past the
guard before pressing again, as the menu tests do.
