Zdenek since you added the code to thread_jumps to incremental update the DOM information, could
you comment on this bug?
(Note I have seen this in more than just this testcase which is superficial).
I almost want to say if we reach a threshold to just free the DOM information since it is no longer
profitable to do the incremental update.
