Drag-and-drop: keep cursor set by user, if any (#5467) 

We used to always set the cursor to `Grabbing` when a drag and drop
payload is set, but this shadows user code trying to set an alternative
cursor (e.g. `NoDrop`). This PR no only change the cursor to `Grabbing`
if is way previously set to `Default`.
