Looking at the diff from #40572, which introduced the issue, it seems that cancelReqs is only called here, and you ended up removing it as the fix. Does that mean we should just remove the other references to it as well?

That's a quick fix to fix our released branches while we work on the actual fix, hence I only removed the line causing the issue and left the rest of the feature. Soon I'll make a PR with tests and a proper fix.

I think the CI failure is unrelated, I'm rerunning the tests. I also enabled auto-merge.
