What assertion is hit?

This probably needs a test.

Early returns would be better.

hasClass(), it is said in the changes explanation. Do you want me to be more explicit? Where exactly?

There were quite many tests crashing because of this in debug mode. Actually the bot has an early exit because of those crashes:

Exiting early after 28 crashes and 22 timeouts. 27309 tests run.
121 failures
9 new passes
11 missing results

The results can be seen at:
http://build.webkit.org/results/GTK%20Linux%2064-bit%20Debug%20WK1/r164101%20(6827)/results.html

I think the functionality is quite well covered with the current test set. I could add the info to the changelog instead. Do you still want me to add the test?

Ok. I'll change this.
