QML ListView with sections, highlightRangeMode set to ListView.StrictlyEnforceRange and clip set to true

[FabioAncarani]

Hi all,

trying to work with ListView in QML, I cannot understand why setting clip to true and highlightRangeMode to ListView.StrictlyEnforceRange (to have currentIndex updated), I cannot see the first section header (the white rectangle with letter 'A').
Removing the clip, I can see the first section header but scrolling is strange.
Removing the ListView.StrictlyEnforceRange everything works (even when clip is set to true)
The ListView.StrictlyEnforceRange option is not compatible with sections?

Qt version is 5.14.2.

Example code is:

    Item {
        width: 100
        height: 200

        ListView {
            anchors.fill: parent
            highlightRangeMode: ListView.StrictlyEnforceRange
            clip: true
            model: ListModel {
                ListElement { section: "A" }
                ListElement { section: "A" }
                ListElement { section: "A" }
                ListElement { section: "B" }
                ListElement { section: "B" }
                ListElement { section: "C" }
                ListElement { section: "C" }
                ListElement { section: "C" }
                ListElement { section: "D" }
                ListElement { section: "D" }
                ListElement { section: "D" }
                ListElement { section: "E" }
                ListElement { section: "E" }
                ListElement { section: "F" }
            }

            delegate: Rectangle {
                width: parent.width
                height: 50
                color: "black"
                Text {
                    anchors.centerIn: parent
                    color: "white"
                    text: model.index
                }
            }

            section.property: "section"
            section.delegate: Rectangle {
                width: parent.width
                height: 50
                color: "white"
                Text {
                    anchors.centerIn: parent
                    color: "black"
                    text: section
                }
            }
        }
    }
