I've likely caused this with #54776. @imotov, would you like me to look at it or do you want it?

[imotov]

@nik9000 I assumed it's me but I didn't start looking into it, so if you have time, please go ahead.

[nik9000]

I'll pick it up now.

Should be fixed by 12cf663. Let me know if that causes anyone any trouble.
