[Bug] Drag & drop within web widgets

Hello,
I'm trying to write an application for OpenBoard (electrical diagrams) that uses drag and drop within the application.
Outside OpenBoard (chrome or FF) it works without a problem but if I try to transform the code into an OpenBoard application, the drag and drop operations result in the message "Are you trying to drop the object(s) inside the widget?" (« Essayez-vous de déposer l’objet à l’intérieur du widget ? » en français)

Is there a work around this?

Thank you
Christian
