Fullscreen mode is reset on window size change or screen lock

When fullscreen mode is used with dynamic resolution, current work area size and auto scale factor, the resizing of the window like split screen mode or free form window or when rotating a device or locking and unlocking it causes fullscreen mode to be reset - shows a bottom bar with sessions and the floating bar at the top.

Video timestamps:
0:17 - screen lock and unlock - bars show up, screen is not resized, should instead be exactly the same as before locking the screen

0:34 - entering split screen (or free form window also) exits active RDP session and shows menu, should instead just resize the session accordingly to new window size, and keep previous fullscreen state (not show bottom bar and floating top bar), and not draw behind top black inset with system ui of a window (sometimes it doesn't, sometimes it does, should be always like in 0:44)

0:49 - resizing window should not reset fullscreen state, just resize the fullscreen to new working area. Now it shows bottom bar but doesn'tt show top floating button, when this bugged fullscreen / not fullscreen mode is present

1:20 - sometimes resizing window causes the cursor to become corrupted
