@mcc it took me forever to understand why, when I accidentally pressed CTRL-O instead of ALT-O in VS Code, I got a random popup that said that the application was ready and then it became completely unresponsive.

Turns out it was showing the "open file" dialog *behind* the window, but still somehow making it modal. Because Wayland? I dunno.

Now I at least know how to fix it without having to close and restart Code, but it was driving me absolutely nuts for a while.
