Unsure if this is needed, but definitely not harmful and an easy/safe check.

github-actions · 2026-04-06T14:04:22Z

This change is marked for backport to 4.6 and it does not conflict with that branch.
The command used to test backporting was

git checkout 4.6 && git cherry-pick -x --mainline 1 56acdf43c1b75ef2a8bad99472d2cee13f485a5c
