When more than 2 Sprites are assigned to "Sprite Shape Profiler" and after that when Undo operation is performed then it causes the Editor to throw ArgumentOutOfRangeException continuously, refer the attached video.

Steps to repro:
1. Create a new project with 2D Template
2. Project window > Create > 2D > Sprite Shape Profiler
3. Sprites > Add 2 Sprites Selector > Assigned Sprites
4. Edit > Undo Inspector
5. Edit > Undo Inspector > Repeat 2 times

Actual Result:
ArgumentOutOfRangeException is thrown on performing Undo operation when more than 2 sprites are assigned to "Sprite Shape Profiler" earlier

Expected Result:
Undo operation is performed gracefully
