UnityEvent drawer no longer handles events in non-public fields correctly



How to reproduce:
1. Open the attached "" project
2. Open "SampleScene"
3. Select the "Listener" in the Hierarchy
4. In the Player Input component inspector, open the "Events" and "Player" foldouts
5. Try to set the Fire() event listener to Script.Click()

Expected results: The Script.Click() method can be chosen
Actual results: Only static parameters can be chosen

Reproducible with: 2019.2.7f1, 2019.3.0b1, 2020.1.0a2
Not reproducible with: 2018.4.7f1, 2019.2.3f1, 2019.3.0a11

    2019.2.8f1 patch didn't fix the issue completely. Some methods are still missing, eg can't assign Animator.SetTrigger(string) to a UnityEvent<string> so that the event argument is automatically routed to the handler.

    This is now fixed for me in Unity 2019.2.8f1. But I had to re-build a lot of my Script.Click() methods. Not all but many of them. Can anyone else validate this?

    Set up the event as normal using static parameter approach them switch to inspector to debug mode and set the event's ”Mode” to ”Event defined”.
    It'll show as ”missing” on return to ”non-debug” mode but it still works.

    2019.3.0b4 fixed the issue for me as well. 2019.1.14f1 works fine too.
