vmpstr@, looks like another clip stack bug, although I'm guessing it's the same underlying cause as the previous one.

Feel free to pass it on. CHECK failures can wait on wangxianzhu@.

Yeah this looks like the same issue as before. ( crbug.com/869264 ) That bug is for some reason detected as fixed but afaik no changes have happened. The context of my investigation is on that bug.
