Good magic and bad magic

Most times the magic tool works but sometimes is not progressing, you have the spinner in bottom left of screen but nothing happens and cancel has no effect.

In console there is a “Uncaught (in promise) DOMException: The object could not be cloned.” message

It happened to me too, I think the message after pressing cancel was “Clearing after Virtual finger” (or magic finger?) and it didn’t go away. First time I refreshed page to get rid of it, second time I selected Virtual Finger tool and the message dissapeared. So it may be just visual issue.
