CQ crashed on this CL so I'm unchecking it while investigating. Sorry for
inconvenience.

No problem!  This CL is no rush.

Looks like Rietveld is not quite reliable today that CQ's requests sometimes
expire and fail to get the json back, which causes the crash. I see that all
trybots are green now, so would you just manually commit this CL once it gets
approved? Thanks!
