The drag is blocked in cefclient\browser\client_handler.cc ClientHandler::OnDragEnter():
// Forbid dragging of link URLs.
if (mask & DRAG_OPERATION_LINK)
return true;
Howevever, it appears that this check is wrong in current CEF versions since |mask| is DRAG_OPERATION_COPY | DRAG_OPERATION_LINK | DRAG_OPERATION_MOVE when dragging both links and fragments.
The check should be fixed to properly differentiate between links and fragments.
For your purposes you can remove this check and all dragging operations will work in cefclient.
