Initiating a drag event from within an HtmlDialog window does not fire drag-and-drop events until mouse button is released



With SU2017 and CEF v52, initiating a drag from within the browser does not fire the drag-and-drop events until after the mouse button is released. Also, the first drop operation is ignored and the drag cursor is set to the “do drop” cursor. Many issues related to drag-and-drop when initiated from within the dialog window. Initiating a drag from another window and dropping onto the CEF dialog window works great! Running the html5 code in Edge works as expected so seems to be only an issue with CEF.

Does anyone have a fix or work around?
