Support for UI Toolkit Elements in PropertyDrawers

[VikingPingvin]

Describe the bug When TriInspector is added to the Unity project, CustomPropertyDrawers won't work with UI Toolkit elements, but the UGUI system. I suspect the behavior is similar to what is explained in this thread: https://discussions.unity.com/t/property-drawers/724398/95

Expected behavior I'd like to be able to use public override VisualElement CreatePropertyGUI(SerializedProperty property) in my custom propertyDrawers that are not using any TriInspector functionality.

Code Sample

[CustomPropertyDrawer(typeof(WhateverPropertyAttribute))]
public class WhateverPropertyDrawer : PropertyDrawer {
    public override VisualElement CreatePropertyGUI(SerializedProperty property) {
        var container = new VisualElement();
        container.style.flexDirection = FlexDirection.Row;

        var propertyField = new PropertyField(property);
        propertyField.Bind(property.serializedObject);
        propertyField.style.flexGrow = 1; 
        container.Add(propertyField);

        // Create buttons and add them to the container
        Button button1 = new Button(() => Debug.Log("Button 1 pressed")) { text = "B1" };
        Button button2 = new Button(() => Debug.Log("Button 2 pressed")) { text = "B2" };
        Button button3 = new Button(() => Debug.Log("Button 3 pressed")) { text = "B3" };

        container.Add(button1);
        container.Add(button2);
        container.Add(button3);

        return container;
    }

    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label) {
        EditorGUI.PropertyField(position, property, label);
        Debug.LogWarning("UI Toolkit not supported, falling back to IMGUI.");

    }
}
