  But we have a selection, that's the point. We just don't have a datasource on the selection.
  
  Relevant code in KWin which goes into the code path:
  
    if (selection) {
                         xclipboard->sendSelection(selection);
                     } else {
                         xclipboard->sendClearSelection();
                     }
  
  We do check whether we have a selection. So from KWayland Server side we have a selection. If we would not have a Selection it would go into sendClearSelection.
  
  That we don't send any useful DataOffer doesn't really matter. We also don't check whether the DataSource has any offers.
