Feedback InspectorMode not serialized when unity restarts - Regression

So there is this one minor thing, I'm quite annoyed about for a few years now, that was working in up to Unity 2017.4, but not in any newer versions. I just recently understood why, so I'm opening this thread in the hopes of getting a fix for the issue:

I really like having two inspector tabs open at all times, one with the normal inspector modde, and one with debug:


When having this setupand restarting Unity on version 5.6, the inspectors will keep their inspectormode. For all newer versions, the debug inspector will become a normal inspector as well.

And here is the cause for this:

Unity 5.6

Code (CSharp):

1. internal class InspectorWindow : EditorWindow, IHasCustomMenu
2. {
3.     public InspectorMode m_InspectorMode = InspectorMode.Normal;
4.     ...
5. }

Unity 2019.3

Code (CSharp):

1. internal class InspectorWindow : EditorWindow, IHasCustomMenu
2. {
3.    InspectorMode   m_InspectorMode = InspectorMode.Normal;
4.     ...
5. }

Looks like a small refactor change to make a cleaner API. The problem is, that the public scope also implicitly serialized the field (which makes it persist between unity sessions). So the refator I wish for is

Unity 2019.3

Code (CSharp):

1. internal class InspectorWindow : EditorWindow, IHasCustomMenu
2. {
3.    [SerializeField]
4.    private InspectorMode   m_InspectorMode = InspectorMode.Normal;
5.     ...
6. }

That would add back the possibility to have Debug Inspector Windows in layouts that persist when restarting the editor.


Am I onto something here, or was this change made on purpose?

 

Thank you, to whoever fixed this in the new unity version (I noticed it in 2021.1.5f1). You made me very happy!
