Null Reference using IMGUIContainer and array fields
In my project I have a custom editor for a subclass of (a subclass of) a ScriptableObject that is using UIElements. In order to show its base classes editor, I am using an IMGUIContainer.
public override VisualElement CreateInspectorGUI()
{
this.tree = GrowableEditor.BuildContainer("TrackInspector");
var baseInspector = new IMGUIContainer(this.OnInspectorGUI);
this.tree.Add(baseInspector);
return this.tree;
}
This is working, but when I highlight the value in any serialized array's size field I get the following Null ref
NullReferenceException: Object reference not set to an instance of an object

It does not seem to cause any major issue, other than the error spam and resetting the scroll position, but was wondering if there is a way to avoid this?
