Going to merge this as the failures are unrelated.

I'd consider the usage of snapshots as the current ones are quite big making it hard to know what had changed.

The snapshots aren't meant to be reviewed by humans right now, the files the tests write to the filesystem are - the tests are just a failsafe. I'll make change to this bit by bit (just as we've added the matrix test and new dimensions), but it'll take some time.

@erezrokah I updated the format of the snapshot tests in #4239, should be significantly better to read diffs now!
