Summary [Mac] Crash during scroll when latched

Reported 2014-05-18 22:38:23 PDT
It's possible to be latched to a DOM element, then attempt a new scroll event where the hit test for the mouse event returns NULL for the target element. When this happens, the NULL element is dereferenced without a NULL check resulting in a crash. This patch corrects this mistake.
