Is this still failing? I couldn't reproduce it Go tip on my machine.

From the dashboard, it looks like it may have been fixed by CL 316649.

I think we can call this fixed for now. We can reopen if it happens again. Thanks.

Sorry about that. This is #28643, and improvements to that should follow after #34744 is done.
