SettingsProvider.OnGUI API is called after OnDeactivate when exiting the Play Mode

How to reproduce:
1. Open the user's attached "SettingsProviderBug" project
2. Open the "Edit > Project Settings> Test" window from the menu
3. Enter the Play Mode in the "SampleScene" Scene
4. Exit from the Play Mode

Expected result: Only the OnDeactivate method is invoked when exiting the Play Mode
Actual result: When exiting the Play Mode, SettingsProvider methods are invoked in the following order: four times OnGUI() is invoked, then OnDeactivate() and OnActivate()

Reproducible with: 2019.4.36f1, 2020.3.30f1, 2021.2.14f1, 2022.1.0b10, 2022.2.0a7

Note: The issue is troublesome when setting up/releasing resources that are expected to be available in the OnGUI() method
