+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
