Show Header for Inline Material Editor

[MPierer]

Using the Inline Editor for Materials it would be nice to see the complete Material Editor, including Header (Shader and Edit Button).
[InlineEditor] public Material mat;

Possible impl in InlineEditorElement.cs

public override void OnGUI(Rect position)

...
      if (_editor != null && shouldDrawEditor)
      {
                GUILayout.BeginArea(_editorPosition);
                bool isMaterialEditor = _property.Value as Material;
                if (isMaterialEditor)
                {
                    GUILayout.BeginVertical();
                    _editor.DrawHeader();
                    GUILayout.EndVertical();
                    lastEditorRect = GUILayoutUtility.GetLastRect();
                }
                GUILayout.BeginVertical();
                _editor.OnInspectorGUI();
                GUILayout.EndVertical();
                Rect lastEditorRectInspector = GUILayoutUtility.GetLastRect();
                if (lastEditorRectInspector.width > lastEditorRect.width)
                    lastEditorRect.width = lastEditorRectInspector.width;
                lastEditorRect.height += lastEditorRectInspector.height; 
                GUILayout.EndArea();
            }
