Hi @Hexilee please append CHANGELOG for this bugfix.

And do we need to cherry-pick this PR into release-2.1?

Hi @Hexilee please append CHANGELOG for this bugfix.

And do we need to cherry-pick this PR into release-2.1?

I'm sorry to forget that, I will create another PR to update CHANGELOG. This bug is introduced after release-2.1, so it's unnecessary to cherry-pick.
