Cannot expand a private list of variables when using the Debug Inspector mode

Inspector Framework


How to reproduce:
1. Open the attached project
2. Open SampleScene
3. Select GameObject in the Scene Hierarchy
4. Switch inspector to Debug mode (click the dots on the top right corner of the Inspector > select Debug)
5. Observe MyScript has a private list My Private List of ints
6. Try clicking the arrow to expand the list
7. Select MyFile in Project assets
8. Observe MyFile has a list MyList
9. Try clicking the arrow to expand the list

Expected result: You can expand the list to monitor the list values
Actual result: You cannot expand the list

Reproducible with: 2020.2.2f1, 2020.2.5f1, 2021.1.0b4, 2021.1.0b8, 2021.2.0a6
Not reproducible with: 2018.4.30f1, 2019.4.21f1, 2020.2.1f1, 2021.1.0a1, 2021.1.0b3

Workaround: Use [SerializeField] to display values in Normal Inspector mode, but this will allow modifying the values

1. MyFile MyList field in inspector can not be expanded to inspect content in Normal mode as well

    I am using version 2021.3.4f1 and this is still a problem.
    The add comment button is overlaying the top of the elements that I am trying to expand. I cannot expand them and use them because the UI has the focus on the Add Component button.

    Reproduced in 2020.3.10f1 and it's driving me crazy.
    Time to make everything public! :)

    There is a workaround for this. Make the field public, recompile, expand in the Inspector and then you can change it back to private. The list/array will stay expanded.

    Also in 2021.1.12f1 and yup super annoying.

    As a work around for now, you can add the [SerializeField] as suggested, then expand all private vars in the Inspector (debug mode), then remove the [SerializeField] tag.

    It only seems to be the top level that cannot open, lower levels operate as normal.

    P.s. same goes for arrays, anything expandable it seems

    I second this. Still an issue in 2020.3.3f1. One thing that was quite handy in Unity 2019 was that in debug mode you could expand these lists. Now in order to check them you must make them public, which exposes them, which I'm not always a fan of. I just like my privacy ok! Now I need to find a corner to cry in... I still love Unity regardless. But a fix would be AWESOME! Thank you please
