3.6%-25.4% regression in rasterize_and_record_micro.top_25 at 577716:577760

Similar increase seen in multiple stories. I think this is worth at least bisecting to see if anything comes up.

Probably due to extra clip node on image elements. I created a revert. Will reland with a version that exclude image elements.
