Editor freezes on script recompilation when a custom window is open and it has a reference to a Serializable VisualElement class
How to reproduce:
1. Open the attached 'project-1215840.zip' project
2. In the Editor select 'Bug' > 'Bug_Test'
3. Make a change in 'Bug_Test.cs' script and click on the Editor to recompile scripts
4. Try clicking anywhere in the Editor or resize the 'NewUI' window (only the top tool-bar is responsive)
Expected result: Editor does not freeze
Actual result: Editor freezes indefinitely
Reproducible with: 2019.2.21f1, 2019.3.1f1, 2019.4.9f, 2020.1.0a23, 2020.2.0b1
Could not test with: 2017.4.37f1, 2018.4.17f1 (UI Elements not available)
Note: the custom window includes a property that derives from VisualElement. During assembly reload that property is serialized, even though it is private. This puts the window into a bad state freezing the editor. Putting the [System.NonSerialized] attribute on the property avoids the freeze by making sure it is never serialized during assembly reload.
