How to reproduce:
1. Open the user's attached "DS-Test-Project" project
2. Open the "Drawing" Scene
3. Make sure that the Game view is in Simulator mode
4. Enter the Play Mode
5. Change the Game view mode to the Game
6. Try to draw on the sides of the Game view (outside of the Simulator's safe zone)

Expected results: Whatever is drawn on the sides stay
Actual results: Only what has been drawn inside the Simulator bounds used before switching mode stays

Reproducible with: 1.2.0-preview, 2.2.4-preview (2019.4.25f1, 2020.3.7f1, 2021.1.0a9), 2021.1.0a9, 2021.1.6f1, 2021.2.0a15
Could not test with: 1.1.0-preview and earlier because of the CS0103 error

Notes:
- Entering the Play Mode in the Game mode, switching to the Simulator mode, and switching back to the Game mode doesn't make the drawing stay only in the safe zone
- Since Unity 2021.1.0a9 the Device Simulator is no longer a package and is built-in
