Bug Addressables play mode script setting ignored when running Playmode tests in Editor

As the title says: When I run my PlayMode tests in the Unity Editor all the addressable operations ignore the current selected play mode script and use "Use Existing Build". I tried forcing the current script selected to the fast mode before running the test but the Editor still does not load the project assets using the AssetDatabase (Use Asset Database) and tries to load remote bundles.

Is this a bug or some limitation that is not mentioned in the docs?

Unity: 2020.3.20f1
Addressables: 1.18.19 (Verified)
Test Framework: 1.1.30 (Verified)

great...

 

I'm facing the same problem here.
Same unity version

 

So I figured out what's wrong...

The addressable asset system is saving something to the player pref. That thing is what the editor is using to locate the asset in the asset database.

I was deleting the player pref keys on start
