> I agree to accept this PR. 'try to upstream first', it's true. but it depends on what kind of problem we resolve. In this case, we can enable it in Crosswalk firstly, not touching Chromium-crosswalk. so it's ok for me.

@yongsheng, I'm sorry I could not agree u unless this fix is correct followed by upstream way. If patch change like that, I'm okay to give my lgtm.
