Of course if you read the code that is exactly what the method does before calling -[UINavigationItem setAttributedSubtitle:] but surely this wacky behavior is intentional and must have gone through some sort of review, right?

What I don’t get is how Mail is able to make this San Francisco but Passwords somehow ends up with Helvetica for both its collapsed and expanded state subtitles

@saagar wouldn't be surprised if this were hardcoded based on bundle ID
