Subject: [PATCH 7/7] Fix gr-hovercard-behavior under Firefox.

Firefox doesn't implement toElement/fromElement (they're not in the spec,
and were implemented by Chrome apparently for compatibility with IE), but
does implement target and relatedTarget, which are part of the UI Events
spec (https://w3c.github.io/uievents/#interface-mouseevent).

Bug: Issue 13175
