      Description

      Description

      JavaScript library imports are not reachable inside inline QML components i.e. those defined with component New : Existing syntax.

      Here's an almost-minimal reproducible example:

      main.qml
      import QtQuick 2.15
      import QtQuick.Controls 2.15
      import QtQuick.Window 2.15
      
      import "Lib.js" as Lib
      
      Window {
          width: 640
          height: 480
          visible: true
          title: qsTr("Hello World")
      
          component C : Rectangle {
              width: 200
              height: 200
              color: "#d1d1d1"
              // Label from Controls is reachable
              Label {
                  anchors.centerIn: parent
                  // But Lib is not
                  text: Lib.getFruit(1)
              }
          }
      
          Column {
              anchors.centerIn: parent
              Label {
                  text: Lib.getFruit(2)
              }
              C {}
          }
      }
      

      Stateless JavaScript library:

      Lib.js
      .pragma library
      
      const FRUITS = {
          APPLE: 1,
          ORANGE: 2,
      };
      
      function getFruit(n) {
          return Object.entries(FRUITS).find(([_, v]) => v === n)[0]
      }
      

      Expected result

      All imports should work, named imports are should accessible inside inline components just the same as from outside.

      Actual result

      qrc:/main.qml:21: TypeError: Cannot call method 'getFruit' of null
      

      Version

      Can be reproduced on both Qt 5.15.x branch and Qt 6.1.2.
