Hello @maxperei! Thank you for your quick response.
I will try to use your commit as a patch from my composer while waiting for a new tag 4.1.

And I am closing this PR!

Hello @delyriand

Let's merge this one on 1.x compat branch. As it was previously that parameters on 4.0, this patch is correct.

Thank you 🙏
