Implement new behavior for popovers contained within invokers
In this case:
<button popovertarget=foo>Activate
<div popover id=foo>Clicking me shouldn't close me</div>
</button>
clicking the button properly activates the popover, however,
clicking on the popover itself after that should not close
the popover. It currently does because the popover click
bubbles to the <button> and activates the invoker, which
toggles the popover closed.
This CL changes that behavior so that clicks on the popover
in the case above no longer re-invoke the popover.
