Fullscreen does not remember previous resolution.

In past versions, exiting full screen mode would return the PC client to its previously chosen resolution . For example, I play on a 4k monitor, but in windowed mode, I play in 1440p. Last year, when I would exit full screen with the keyboard shortcut, the screen would return to its former size, but at some point, it just started becoming a window with the screen's full resolution. I play on three Windows devices, running both 10 and 11, and the behavior is the same. This makes playing the game in full screen far more of a pain, and I avoid something I used to do constantly, lessening my enjoyment of Arena.
