Is this the same as  crbug.com/703861  , fixed by https://codereview.chromium.org/2767093003/ ? I don't have access to that bug - feel free to dup if it's the same.

Comment 2 by geoffl...@chromium.org, Mar 22 2017 

Not quite the same but it should be fixed by fixes for the other bugs.

Comment 3 by geoffl...@chromium.org, Mar 22 2017 

Will keep it open to verify that it gets fixed by the CL.
