Hi!

After uploading some images, the copping behaves very strangely until I save the page again and reload it. Then it works as expected. I made a small screencast to show the behavior (sorry, no sound, but you will get the gist of it): https://youtu.be/RVUpWCw0M6M

Just to confirm, I did see this report and started looking at it but as of yet don’t have a fix.
