[LH2417] Disappearing text after closing copyholder

This appears to be related to the split-screen disappearing-text bug, but while playing around with the tutorial binder for new stuff (and finding the aforementioned bug), I also found a different way to make text vanish… I’m not sure whether this is a known bug as well, but if you close a floating copyholder window, even if there’s only one file open, random swathes of text will also disappear.

This happened when I first had split screens, opened the copy holder in both of them, made them float, then closed one of the files. I don’t remember right now whether the copyholder that caused this when closing was from the closed file or the still open file.

Hello! I believe this is connected to the aforementioned bug. I’ve updated it with your comments. Thank you!
