To Reproduce (If applicable)

1. Press Play button.
2. Search through the Search field for a specific object (probably must be an one generated at runtime).
3. Click on the object in the search results to focus.
4. Click the x in the right marker of the Search field to turn off the filter.
5. Exit PlayMode by press Play button.
6. Exception Occurs.

• It is caused by the use of search fields.
• There is a specific game object that causes the occurrence. Not all game objects are affected. I don't know what they have in common.
• Cannot be reproduced in the sample scenes in this library.

This is a simple but workaround code. It is not a radical solution, but at least it does not raise an exception, so the hierarchy view does not disappear.
