Outlook messages deleted when dropped in Edge

[gabbsmo]

I am maintaining a web application that receives files via drag and drop. In the current stable version of Edge I can drag a message from Outlook and it will be uploaded. If I use Chromium Edge Beta (or Google Chrome) the message will be uploaded as expected, but is also deleted from Outlook. In SharePoint Online document libraries the message is not deleted so I guess there is something missing in my JavaScript code.

Where do I/we go from here? If you need a small repro I will need some time to develop that.

Thank you.

The issue is that the drop target needs to set the correct dropEffect. There is a thread on the issue:
