Additional Editor Instance appears to be still active when exiting Play Mode and closing the Editor window

Steps to reproduce:

1. Create and open a new project
2. Install the 'Multiplayer Play Mode' package
3. Create a new Play Mode Scenario
4. Add an 'Additional Editor Instance'
5. Switch to the new Play Mode Scenario
6. Enter and Exit Play Mode
7. Close the other opened Editor instance
8. Observe the Play Mode Scenarios window

Actual results: The Instance has an info bubble saying 'This instance is currently active...'

Expected results: There is no info bubble saying 'This instance is currently active...'

Reproducible with versions: 6000.6.0b10, 6000.7.0a4, 6000.7.0a5

Can’t test with versions: 6000.0.82f1, 6000.3.23f1, 6000.5.10f1, 6000.7.0a3 (No info bubble)

Tested on (OS): Windows 11 Pro (25H2)

Notes:

• It is only a visual issue. It's gone after adding/removing a scenario or by reopening the window
• Deactivating the Players in 'Window -> Play Mode -> Active Scenario' doesn't resolve the issue either
