Editor performance drops when a Game Object with a Custom Editor has its element expanded
Reproduction steps:
1. Open the attached project: "1408562.zip"
2. In the Project window go to Assets > MackySoft > MackySoft.SerializeReferenceExtensions > Example
3. Open "Example" Scene
4. In the Profiler window, set Target Selection to Editor and Record profiling information
5. Select the "Example" Game Object in the Hierarchy window
6. In the Inspector window under "Commands" expand "Element 0"
7. Observe the Profiler
Expected result: Expanding elements within the Inspector window should not reduce performance
Actual result: Performance drops after expanding the elements
