3892 Page title preference surprisingly case sensitive

The preference for setting the browser page title on works was case-sensitive, which was kinda unexpected. The downside to making it case insensitive, of course, is you can't do "Fandom - FANDOM - Title - TITLE - Author - AUTHOR" to get "Fandom - Testing - Title - A Work Named Sue - Author - testy" but that seems pretty edge case-y, especially since adding labels makes the title so long...
