Correct expectations for pointerevents after slot changes.

These 3 points were missed previously:

• The mouse pointer moves off from the shadow_host to click done.
• After slot removal, the slotted_child remains un-rendered and
  also doesn't appear in the parent.children list. So the
  slotted_child is effectively disconnected therefore not expected
  to receive any following event. Firefox behaves this way too.
• The down/up events at parent are also dispatched to shadow_root.
  Both Chrome and Firefox behaves this way, matching the spec [1].
