[Site Isolation] Hovering in and out of an iframe which has mouse events zoom
set only works occasionally

Reviewed by Sihui Liu and Ryan Reno.
With site isolation enabled, mouse events transitioning to remote frames
would skip calling updateMouseEventTargetNode, preventing mouseout events
from being dispatched for the previously hovered element. This caused hover
animations to work inconsistently. This change ensures
updateMouseEventTargetNode
is called before returning for remote frames, allowing proper coordination
across process boundaries and adds a test for verification.
