Thank you!

Is this affecting a hydra job we have?

[sternenseemann]

xml-conduit has a reverse dependency closure of 3759, so that's probably why. Maybe better to wait on the next rotation for this or merge into staging…

[maralorn]

Ah, no. I was more curious about why you are fixing a 9.12 build. I also noticed that xml-conduit is broken because I am playing with reflex-dom on 9.12 and the lack of any hydra jobs to actually determine if they are working is slightly annoying.

[maralorn]

I am fine with merging anywhere.
