With "Recompile After Finished Playing" preference selected, changing script in play mode and saving the changes, does not reflect in Unity.

Note:
1. Refer attached video
2. Workaround #1: Right-click in Project window > Refresh
3. Workaround #2: Send Unity to the background and then back to the foreground

Steps to reproduce:
1. Open Unity > Create new project
2. Assets > Create > C# script
3. Edit > Preferences
4. General > Script Changes While Playing > Recompile After Finished Playing
5. Play scene
6. Open script > Edit script
7. Stop play mode in Unity

Actual result:
Unity does not recompile the changes made to the script

Expected result:
Unity compiles the script when it exits play mode
