Description

Tested with 8.1.0rc1, 8.1.0 and 8.1.3 in Windows 10
Dragging works normally in Edge
Dragging doesn't work in Chrome, Firefox or IE11
the "draggable" property isn't found in DOM in the cases where it doesn't work
Reason is probably DragSourceExtensionConnector, where the extend method calls BrowserInfo.get().isTouchDevice() (have not verified)
Sample project:
drag-and-drop.zip

Research direction

Start with the linked drag-and-drop sample project and reproduce the failure in Chrome, Firefox, and IE11 on Windows 10. Inspect DragSourceExtensionConnector.extend and the BrowserInfo.get().isTouchDevice() check; done means the draggable property is present and dragging works in the affected browsers.
