Patch by Kevin Ellis <kevers@chromium.org> on 2012-10-25
Reviewed by Antonio Gomes.

Source/WebCore:

Inidcate that an <embed> element can respond to
mouse click events, since mouse events are forwarded
to the plugin.  Fixes touch adjustment at a plugin
boundary.  Prior to the patch a clickable element
adjacent to the plugin would capture synthetic mouse
events from tap gestures that spanned the plugin
boundary.

LayoutTests:

candidates for touch adjustment.
