<h3>Log Message</h3>
<pre>REGRESSION (<a href="http://trac.webkit.org/projects/webkit/changeset/167689">r167689</a>): Hovering file name in a file input causes a crash
https://bugs.webkit.org/show_bug.cgi?id=132214
Reviewed by Andreas Kling.
Source/WebCore:
The bug was caused by callDefaultEventHandlersInTheBubblingOrder unconditionally
accessing path.contextAt(0) even if the event path was empty.
Fixed the bug by exiting early when the event path is empty.
Test: fast/events/shadow-event-path-2.html
* dom/EventDispatcher.cpp:
(WebCore::callDefaultEventHandlersInTheBubblingOrder):
LayoutTests:
Add a regression test.
* fast/events/shadow-event-path-2-expected.txt: Added.
* fast/events/shadow-event-path-2.html: Added.

+ REGRESSION (r167689): Hovering file name in a file input causes a crash
+ https://bugs.webkit.org/show_bug.cgi?id=132214
+
+ Reviewed by Andreas Kling.
+
+ The bug was caused by callDefaultEventHandlersInTheBubblingOrder unconditionally
+ accessing path.contextAt(0) even if the event path was empty.
+
+ Fixed the bug by exiting early when the event path is empty.
+
+ Test: fast/events/shadow-event-path-2.html
