There is no way to test it in core-libs. One can argue if the canonicalize method is in the right file, but that should be a separate discussion.

Sorry Ralf, yes you are correct. What a strange arrangement.

The test change seems fine in that case.

I'm afraid I can't comment on the actual fix, sorry.
