Yes, unfortunately, d&d in Python panels is very buggy. over the course of several years, I've seen all sorts of issues including this.

First, make sure in your dragEnterEvent you store the mime data somewhere and then the next time you enter the widget, check if such data exists and reject the event if it does.

See if it works for you, you might need to do the same trick with the dropEvent
