This bug seems to be regression. because This bug is not reproduced at Fx2.

I'll take this.

I think that the patch conflicts to the one of bug 392785. We need to wait it.

Moving to wanted list - even though this is a regression the impact looks pretty small...

text-decoration:line-through seems to have same problem.
Should I file it as another bug ?

I'm resetting bugs which are assigned to me but I'm not working on them and I don't have plan for fixing them in near future.
