Ah, thanks! I indeed had it after a Host block with indentation / paragraph, so I was misled in thinking of them as actual "paragraphs". Putting CanonicalizeHostname at the top of the file indeed works.
So it seems this was a deliberate change, or just accidentally happened to work before. So I guess we can close this.
