Description
Expected Behavior
If a costume's image is completely blank it shouldn't show anything in its thumbnail in the costume list.
Actual Behavior
Sometimes the thumbnail for an empty costume will show you the thumbnail image from a previously selected sprite. The image will be positioned incorrectly.
If the sprite has only one costume and that costume is blank and the dimensions of that sprite are 0x0 it will show this behavior. You must open the paint editor, select a sprite that has a costume, then select a sprite that is blank and has a size of 0x0. The best way to get a sprite that has such a costume is to create a new sprite. Creating a new costume creates a costume that is 2x2 and doesn't show the problem.
Steps to Reproduce
Create a new project
Open the paint editor
In the sprite list area choose Paint a new sprite
Note: the new sprite is created and the paint editor switches to that new sprite. The thumbnail for the first costume has an image of the cat positioned incorrectly on it.
