Bug description

This bug is quite specific and hard to describe, but it's objective enough to be reproducible and, especially, VERY annoying when it does happen. I'll try to explain with words and there's also a video showing it in action.

The bug happens when an app is launched with Super + Shift + number (1-9) (the shortcut that opens a new window of a pinned app, even if it already has an open window). The launched app opens a window on the incorrect display and, worse, does not receive focus (this is the biggest problem). Because of that, it's quite common for me to end up doing wrong actions on the wrong window: closing the wrong tab, start composing a random email or even accidentally deleting something. This can be seen near the end of the attached video.

What seems to happen is that shortcut Super + Shift + Left/Right (move window no another display) doesn't correctly set the new window position. It thinks it's still on the display that it was before. Then, if another window is opened with Super + Shift + number, the new window goes to wrong display and, for some apps (like Firefox), don't receive focus. The focus remains on the window that it was before, either for the same or different app.

The bug sometimes also occur if the window is moved to another display not via keyboard but via Cinnamon panel. I could not reproduce this on the video.

The bug does not occur if new window is clicked, moved or resized before Super + Shift + number is pressed. Some interactions, especially using mouse, will tell Cinnamon to remember the new window position correctly.

Please see video below.

Steps to reproduce

1. pin an app on position 1 (firefox is a good option)
2. open it with super 1
3. move its window to next display with super right
4. try to open a new window of it with super shift 1
5. new window appears on old display and without focus

Expected behavior

a new window of app 1 should be displayed on the new display and with focus

Additional information

I can add any other details or make a new video if it will help. The problem arise on the interaction with Firefox, but I think it'd be easier fixed on Cinnamon. Also, other apps also appear on wrong display, not only Firefox.

No files or tests are named. Reproduce the five listed steps with a pinned app moved using Super+Right, then trace the shortcut handling for window placement and focus. Done means the new window opens on the moved-to display and receives focus, including when the window was moved with the keyboard.
