Hi Daerond,
Thanks very much (and also thanks to the petitions we've received on this issue) for submitting this.
Especial thanks must go to you for your very detailed report here. Precise browser, exact version number, OS and replicatable steps to produce the bug = maximum kudos to you from us. If any future players wish to report general glitches here, then this a really very solid template to bear in mind.
As a very weird coincidence, we're (physically!) with much of the google team tomorrow and wednesday in SF, and we want to ask them some questions about this one as it appears that this is a chrome glitch in their Oct 26 release rather than anything at the HTML5 side at our end.
Having said that, we'll also try for a temporary patch workaround as well in case R16 of chrome doesn't patch the issue.
Thanks again,
SC
