User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:17.0) Gecko/17.0 Firefox/17.0 Build ID: 20120718030544 Steps to reproduce: Visit : https://developer-new.mozilla.org/en-US/docs/CSS/Using_CSS_transitions Actual results: The video is shown as blank space Expected results: The video should be displayed. This is caused by the attributes src and controls being stripped by Bleach. Trivial to fix (but I don't have a working git repo right now). Should block release as it is user-visible and simple to fix.
