Tried to reproduce in a debug build on OS X and hit #12081 first.

[jdm]

http://cbc.ca/ is the URL I was able to reproduce this with after disabling #12081.

[jdm]

My investigations here show a very similar stack to #12047 (ie. link element created as part of innerHTML). I suspect this problem will be fixed when that is fixed.

I can't reproduce this on either website.
