Yunchao: now that those two pull requests have been merged, can this be closed?

P.S. This bug has probably passed under the radar for a while because it had no component and no owner, so please set at least the component in the future. I actually accidentally found it via a Google search.

Yes, I think we can close this issue. Thanks for your reminder that we should set appropriate component(s) for crbug, Kai.
