How to reproduce:
1. Create a new Project
2. Split off the Game View to a different monitor
3. Add Game View Window to the first monitor (Right-click "Scene" -> Add Tab -> Game)
4. Make sure both Game View windows are active
5. Maximize Game View Window on the main monitor (Right-click Game Window -> Maximize)
6. Observe Game View Windows on both displays
Expected result: The Window scales correctly with the resolution and no black bars appear
Actual result: The window scales incorrectly on the second display and black bars appear
Reproducible with: 2022.3.23f1
Reproduced on: macOS Sonoma 14.4 (M1)
Note: Both displays are of different resolutions. Maximising on display breaks the Game view on another, so the order where to maximize does not matter
