Thanks for pointing out the cropping issue, will fix that.
As for pasting, this behavior is indeed targeted at desktop browsers. Unfortunately, I believe this is an iOS limitation, as iOS will not show you the paste option if you press on anything that is not an actual text input.
We will probably just change the message on mobile devices to not include drop/paste (as drag-and-drop is not supported either). Ironically due to this you wouldn’t see the change on your iPad by default anyway, but not sure there is anything we can do about that
