REVISION SUMMARY
  This call to load() triggers a lot of internal stuff in WebEngine,
  including NavigateToEntry, creation (and soon afterwards, deletion) of
  QtWebEngineCore::RenderWidgetHostViewQtDelegateWidget, etc.
  
  I can't see any regression when removing this call.
  
  On the contrary, this fixes a focus issue: when clicking on an
  external link in an email and coming back to kmail, arrow up/down
  didn't work anymore, because the last widget installed as focusproxy
  for the webview (the DelegateWidget above) had been deleted meanwhile.
