When using the sprite editor, if you deselect the sprite being edited then the Sprite panel should disappear. However, only the background of the panel disappears, leaving the fields and labels visible.

Please note that this issue only occurs from the point the package is installed to the next time the editor is closed. The next time the editor is restarted, the issue will no longer occur.

1. Open Unity
2. Open the attached project
3. Open the Package Manger UI and install the 2D Sprite Package
4. Select banana.png in the Project view
5. Open the asset with the Sprite Editor
6. In the Sprite Editor, click in an area outside the sprite to deselect it

Expected Result:
The Sprite panel disappears when the sprite is deselected.

Actual Result:
Some parts of the Sprite panel disappear when the sprite is deselected, but not all of it.

Tested on Windows.
