There’s this strange resizing feature (in Mojang’s sense) in Scratch. If you change its total width or length without actually moving anything else in the sprite, the sprite will mysteriously resize itself, making it look almost completely stupid. Is there a way to fix this?

Adding tiny dots at the corners won’t help much, they’ll become visible when you make the sprite smaller

This is probably added to ensure that the sprite is not too big, it always happens to me. A solution is to create a blank costume and then switch it to the costume after the size is changed.
