Thanks for opening this PR @yanghua and sorry for my late reply.
I think we accidentally addressed this problem already with another PR
(#6202). This was an oversight because you clearly opened the PR before. Since
it basically covers the same functionality, I think we can close this PR.
Sorry for the bad PR management. This won't happen again.---
