Steps to reproduce:

Go to www.chess.com.  Take a look at the puzzle of the day (middle of the screen on the right).  In the latest nightly, it doesn't show anything.  It should be showing a chess board.  If you log into www.chess.com, any game you have running doesn't show correctly either.

I used mozregression to track down when it broke.  The last working date is 2012-12-22.  It was partially fixed in 2012-12-25 but still is pretty bad.

Please post the full output of mozregression if you already did the work to find the regression range.

summary:     Fix for bug 821606 (Turn on WebIDL bindings for Element and HTMLEle
ment). r=bz.

They use optimizely code and this should be Tech evangelism but moving to DOM first so that someone confirms my assumption.

Hmm.  Yeah, I think it is.  This is still using the script version that doesn't restore setters....  We'll see if it gets updated, and if that fixes the bug.

Fix has been rolled out here.
