When I'm drawing i dont' want to accidentally bleed into another image, so I select the sprites and zoom level I want. But when I hit CTRL+Z, not only does it properly undo the last action I did, but it unfortuantely skips back the zoom to default.

This is super annoying. I'm not sure if it's a bug, but it makes drawing super frustrating in Pico8 when using non-standard sizes with the sheet selection tool.
