Fractal shouldn't switch to "no room" when pressing the Escape key
When I click an image in Fractal, I open it in GNOME's default image viewer, Eye of GNOME. EoG, like most image previewers (including things like Nautilus's quick previewer, Sushi) is usually closed with a single keystroke: the "Escape" key.
The problem is that when you press that key, even if it's for a mere 100 miliseconds, Fractal, having become the foreground application as soon as EoG receives the exit signal, interprets the Escape key as "I want to exit/unselect the chatroom I am in" (which I have no idea why anyone would want to do that anyway), making me lose the whole context of the conversation. So either the shortcut key should go away entirely, or you need to put some sort of time measurement on it to react only to keypresses longer than 100-200 miliseconds.
