Check the following change:
https://chromium-review.googlesource.com/c/506009/

It landed using CQ in Gerrit, but the associated  bug #719299 
wasn't updated with the information of the commit.

I see that another change from myself has worked as expected:
https://chromium-review.googlesource.com/c/509448/

Dunno if there's an issue with Gerrit or what,
but reporting it just in case it's a new problem.
