Rationale: It puts the least important information first. For the most part, the CF entry number is irrelevant, so it shouldn't be shown in such a prominent position.
Maybe
<a>title here</a> (number here)
would be a compromise. But looking at the original argument:
""" Clicking the patch header would sort by the patch ID, but that ID would not actually be visible. Effectively resulting in random ordering for the user, so let's just show the ID. """
I would suggest that the actual fix would be to order by title instead of ID.
Or just turn the sorting off.
I'll revert this one pending further discussions, and then we can figure out what we want to put back.
