1. Open the URL. 2. If under "Log:" it does not say 3, 2 the test has failed. (The version and OS and such are all wrong, as I'm using Opera on Ubuntu at the moment...)

Created attachment 24570 [details] Fix I'm a little worried about the performance implications of this, but not sure how the best way to test would be.

Landed in r37800. As a workaround for versions that still have this bug, you can force an update by setting just about any non-class property when you set the class.
