Node Inspector panel doesn't use Custom PropertyDrawers

[noio]

For the data types I'd like to use on my nodes, I've set up a lot of CustomPropertyDrawers, but it seems that the inspector panel ignores those.

I've tried changing my PropertyDrawers from IMGUI to UITK (i.e. OnGUI ➡️ CreatePropertyGUI) but I still think the inspector panel is not using them.
