Not possible to resize SplitView when contents contain ListView with SplitView in delegate

    Description

      I stumbled upon a problem using SplitView in my application, and have created a minimal example to reproduce it.

      What happens is that the vertical SplitView bar cannot be moved if the ListView is at index 0 or 1. If you press the button "2", the splitter can be moved. Pressing buttons 0 or 1 makes it "locked" again.

      The example has a horizontal SplitView, where the left item is a ListView that uses a vertical SplitView in its delegate.

      ApplicationWindow {
          visible: true
          width: 640
          height: 480
          title: qsTr("Hello World")    
          header: ToolBar {
              RowLayout {
                  TabBar {
                      id: theTabBar
                      Repeater {
                          model: listView.model
                          delegate: TabButton {
                              text: index
