Expected: The parameter type of OnChildEnteredTree (underlined) in the dialog is Node, not Object.

### Steps to reproduce

1. Write a public (signal listener) C# function with a Node parameter.
2. Build .NET project.
3. Try to connect some suitable signal (e.g. "child_entered_tree") to that function, and it won't appear in the Pick dialog if `Compatible Methods Only` is on.
