Hello ! I'm on Unity 2022.2.18. Alt-clicking (holding Alt and right-clik) used to recursively folding in and out any type of lists in the Inspector. Now, there is case where it doesn't work anymore, the list doesn't even fold at all. It works in the Project panel, or in Project Settings, but in Inspector not always. It 100% not working when in Debug mode. In Normal, it depends, but I think it works on my custom Editor that still use IMGUI, but not on any Editor that use VisualElement, but not sure about that.
