Bug: Opening a new window when a window is present causes weird behaviour

[zzsmkr]

Description

While having the app running in background, opening a new window (using ctrl+n, moving a tab out of existing window etc.) causes the Files app to start up and load for some time like the option is turned off. Even if "leave app running in background" is turned on, the tray icon will disappear upon closing all windows, but the app wil still run in background. Opening any new windows in this state causes the app to slowly load instead of instantly "popping in" until the background process is terminated completely.

Steps To Reproduce

1. Have files running in background
2. Have a Files app window open
3. Open up a new window without closing the first one
