Labels: Merge-TBD
[Auto-generated comment by a script] We noticed that this issue is targeted for M-62; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-62 label, otherwise remove Merge-TBD label. Thanks.

Comment 9 by abdulsyed@chromium.org, Sep 25 2017 

Thanks allada@ - Since this is marked as RB-Stable for M62, can you confirm if this needs to be merged to M62?
