Steps to repro:
1. Create a new project with 2D Template.
2. Import any texture
3. Open Sprite Editor Window
4. Select "Skinning Editor"
5. Create Vertex
6. Create Edge > Revert

Actual Result:
ArgumentOutOfRangeException thrown continuously when Edges are Reverted.

Expected Result:
Created edges should be Reverted without any exception thrown.
