When user crops multiple sprites > user can misunderstand the blue frame as a selection tool and not as a crop container as it currently functions as. See screen shot.

Prerequisite:
You need a sprite in you assets

Repro:
1. Select the Sprite from the asset
2. In the Inspector, select Sprite mode > multiple
3. Select Sprite Editor
4. Make a manual selection of a graphic element in the sprite
5. Click apply - the sprite is saved with a name_01
6. Drag the selection (Blue frame) to another graphic element in the sprite and apply

Result: the Sprite created before is overwritten by this selection so name_1 containing the graphic element selected in step 6

Expected result: New sprite Name_2 should be created
