autoplay testcase

When you write JavaScript to inject a video into the page by setting the innerHTML of the element that will contain the video, the video does not autoplay even if the tag is set. 

This was the only scenario I could find where autoplay did not work; if one writes the video tag in HTML it works fine, if one creates the video node in JS using the DOM and injects it in the page with appendChild, it works fine, or if there is an existing video element in the DOM to which you add the autoplay attribute and a src, it also works fine.

I think this is the change list that broke it:
http://trac.webkit.org/changeset/65170/trunk/WebCore/html/HTMLMediaElement.cpp

But I'm not familiar enough with the code to know why exactly it's doing this.
