    <thetext>The following layout test is failing on Chromium

media/event-attributes.html

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&amp;tests=media%2Fevent-attributes.html

It is turning very flaky, but not consistently failing except on Webkit Win (dbg)(2).

Probable cause:

    <thetext>scherkus: canplaythrough fires, but seeked doesn&apos;t.  (about 30% flaky when running 10 parallel DRTs running this one test) 
Any chance this is related to bug 73681?  The two tests started failing at the same time (judging from bug-filing times).</thetext>

&gt; vrk it looks like we&apos;re getting flaky progress event counts -- do you think any of your canplaythrough changes in chromium might have caused this?

Shouldn&apos;t be me -- I haven&apos;t landed my changes yet! What&apos;s currently checked in is the same canplaythrough behavior as always.

Actually I haven&apos;t landed my changes yet because I was running into progress event problems as well.... curious indeed!</thetext>

I&apos;m going to mark the test as a flaky crasher as well.

This bug&apos;s been open for a while...would be good to get it reproduced / investigated.</thetext>
