Steps to reproduce:
1. Open the “IN-114248” project
2. Select the “TestSprite” Sprite Atlas in the “Assets/Sprites/avatar.atlas.default.eyeshape.round_plain/main” folder
3. Go to the inspector and under the Show Platform Settings For section, select any platform
4. Change the Format property field value to something else
5. Go to the Objects For Packing section and press the Pack Preview button

Expected result: No errors
Actual result: Switching between different file formats and performing a packing preview generates an "Assertion failed on expression: '(dx - width < padding) || (dy - height < padding)'“ assertion error
