Study: Game import by URL no longer updates the chapter title

I often import games by URL (from both lichess and chessgames) into Lichess studies. Until very recently, if you entered the URL and didn't modify the default title (e.g. "Chapter 3") the study would automatically format the chapter title nicely to include the players' names and ratings. This no longer happens, and it appears to have changed in the last week or so - obviously not a major bug, but it was a nice convenience.
