Chrome browser Bug: Pause button stays when <audio> hits end

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Pranav Kedia]

This is a copy of bug 21739 on Chrome browser. Please see http://code.google.com/p/chromium/issues/detail?id=21739. Here is the description taken from the bug 21739:

In chrome browser, go to http://en.wikipedia.org/wiki/The_Star-Spangled_Banner and click "play" on one of the media files (right hand side of screen). Notice that when the file hits the end, the "pause" button stays a "pause" button rather than turning into "play". This seems kinda broken. (I would expect the slider to return to the beginning and the button to turn to "play").

The fix of this bug is in WebKit/WebCore/rendering/RenderMediaControlsChromium.cpp. Hence filing this bug. Here is the diff of the fix:

It seems the patch was created while current directory was different from the root WebKit one. I'm not sure commit-queue will be able to deal with it.
Please re-submit patch created from WebKit root (where WebCore is a subdir)

This proposed fix has been taken from the function MediaControlPlayButtonElement::updateDisplayType() in http://trac.webkit.org/browser/trunk/WebCore/rendering/MediaControlElements.cpp

Nice.  Thanks.  Do we need to update the test_expectations.txt?
