Can you try roll with less commits and see exactly which one triggered this? 
Although this test isn't changed in this roll, but a test change before this
test might affect it.

[Ken Russell (switch to Gerrit), 2017/04/19 17:47:51]

This failure is really strange. I would have thought it might be an unrelated
change which slipped past the CQ because it didn't run the optional GPU
tryservers, but it really seems to be caused by this WebGL conformance roll.

Thinking about it more -- the addition of the new tests in this CL probably
changed the distribution of tests among shards, and there is probably some bug
in the browser which makes it sensitive to the order in which tests are run,
causing them to fail if they're run in a certain order.

I think we should push ahead with this conformance roll and take the opportunity
to debug it. Updating http://crbug.com/713127 with more information.
