Thank you for your PR, that looks great! I left one question.

Thank you again @asodja! I rebased this PR on release in #17518, since we are going to release a 7.1.1 version with this fix. Then I merged release into master, so the fix is now also there.

I am going to close this PR now, given that I integrated it manually.
