It looks like touch events get swallowed by the video event as long as video controls are present (controls attribute is set on <video>) in Firefox. It doesn't happen in Chrome, and the site is relying on that. Not sure which behaviour is correct.

Hi Sean, wonder if you have any thoughts on this? I've attached a testcase above.
