(That FIXME would just be "if (ownerElement()) ownerElement()->document()->recalcStyle(NoChange);", except that's known to cause a crash in some tests.  If someone wanted to try replacing that fixme with those two lines and running this seamless test on Qt, that data would also be useful.)

That fixed the test. :) Do you have any idea of what tests are supposed to crash by using this? I've run all seamless tests, they are all running as expected.

I've tried this first, but it didn't help.
