      Description

      In Fedora, after moving from qt 5 to qt 6 

      the webview class cannot find the HTML file in the qt resource system

      This only happens in Fedora. tried in fedora 34, and 36. does not happen under Ubuntu 18/20.

       

      here is an example project

      qml:

      import QtQuick 2.0
      import QtQuick.Window 2.0
      import QtWebEngine 1.0
      
      Window {
          width: 1024
          height: 750
          visible: true
          WebEngineView {
              anchors.fill: parent
              url: urlToLoad
              onLoadingChanged: function(info) {
              console.log("Loading changed ... Status = ", info.status)
              console.log(info.errorString)
              }
          }
      }
