Drag & Drop install of widgets does not work with new Microsoft Edge browser

A user from France sent me a bug report, that the installation of widgets like the Document Spy does not work when you drag and drop the widget from Microsoft Edge browser to the My widget sidebar panel of IBM Notes. (You can drag the link, but nothing happens when you drop it)  As a workaround you can use Firefox or Chrome which works on Windows 10 without problems. In the moment i do not have a Windows 10 installation to analyze this problem, but i hope that i will get a Windows 10 machine soon.
