Sorry, @ambv, I could not cleanly backport this to 3.13 due to a conflict.
Please backport using cherry_picker on command line.

Actually, no. I will backport this as part of the gh-119559 backport.

[vstinner]

@ambv: Oh, I wrote a different fix for a similar issue: PR gh-119848. Should I backport it to 3.13?
