User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20121214 Firefox/20.0
Build ID: 20121214030827

Steps to reproduce:

load page  http://www.by-art.com/bubbles/
It's a simple game that uses html5 rather than java.


Actual results:

page loads, but the preview of upcoming bubbles is missing.


Expected results:

There should be 2 partially transparent bubbles in the bottom left.  they're missing.
This worked correctly in Nightly 19, and works in the latest version of Google Chrome.

According to the regression range, this is not affecting 19.  Tracking this regression for 20, however.

Upon further read of bug 812107, it was uplifted to FF19.

I was offline for a few weeks.  This issue was not in FF19 as of Nov 14.  When I got back and updated to FF20 (Dec 9 or 10) was the first I remember seeing it.
