The first commit is based on whatwg/html#9457 and prevents a crash when removing a visible popover.
That spec PR hasn't been merged yet and is currently slightly outdated, but the changes are spread throughout the code so I'm not sure what the best place to add a
FIXME
/AD-HOC
would be.The second commit implements
popovertarget
buttons (and includes a change to top layer elements to prevent a crash when hiding and showing a popover in the same frame).This PR also fixes 29 crashing tests and gains at least 1656 new subtest passes.
(I may start a followup PR to update and implement the remaining parts of the popover spec)
