Editor Bug: Cannot create Array of InputActions

I'm attempting to extend some of the InputSystem features for use in a plugin, but I noticed that whenever I serialize an array/list of InputActions, all sorts of weirdness happens.

Instead of making new array elements, it just duplicates the view of Element 0. No new elements are created, just a window copy of what you see in Element 0. (There's also some off formatting that prevents dropdown arrows, etc). If I delete or alter anything, it happens everywhere.

Is this a simple editor script fix?

 

For now it seems the best workaround is avoiding arrays altogether with the new Input System, and using an InputActionMap if more than one action is needed for a single reference variable. I was hoping to use arrays to use numeric ID#s for actions, and add more options for each action, but no biggie

 

i get simular problem when making a custom editor script. but instead of an array of InputAction, it's an array of
serializable objects with an InputAction. hmm it's 2021 now

 

Still happening... Unity 2020.3.12
