Moving an image can't be undone
1. start from an empty document
2. drag an Image from a palette (see the attached palette. Only reproducible with "image" tags in the palette).
3. drop the image anywhere allowed (e.g. on an empty measure). The image is added and "undo" would remove the image.
4. drag and drop the added image to another position
5. "undo" removes the image
Expected (works in Musescore 2.x):
"undo" restores the image to its previous position.
