This is a follow-up from #1499. Of the repro cases I provided there

URLs appear to not be linked even if the URL as a whole was added (first example), or even if they're just in comments alongside changes (second example—note that I unfolded the top of the diff to get there, not sure if that matters).

URLs do appear to be linked if they're in non-PR code blocks (third example).

The first is fixed with #2066, and the third remains fixed, but the second is still broken.

I can repro both if I visit the unfolded part directly (link) and if I go to the folded diff (link), then unfold the top (one unfold should be sufficient to see the link, at line 51).

Not sure if this is a regression or no.
