Update/Note: we decided to revert this change as users were asking to return this option
How to reproduce:
1. Open the attached "1325047.zip" project
2. Open the Sample Scene
3. Go File -> Preferences -> General -> Script Changes While Playing and set "Recompile After Finished Playing"
4. Enter the Play Mode
5. Open the "script.cs" script
6. Modify the script and save it
7. Go back to the Editor
Expected results: No pop-ups appear
Actual results: A "Recompiling Scripts" pop-up appears - that means that Editor still recompiles scripts, but the Domain Reload is not happening which means that script changes don't apply until you exit Play mode
