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.
