Fixing an old standing issue with 1 line sounds good :)
At first sight, it seems unlikely that issues in this backport will only show up in the backport. So I expect that potential problems will be visible in HEAD as well. If that is true, then it might be safer to target this to 25.0.4, which gives us 3 months testing before we bake it into an LTS.
What do you think?

[crschnick]

Yeah that is fine, that issue has been open long enough for 3 months to not make a huge difference
