Description

When ScrollBar is customized with contentItem, and contentHeight of ListView is smaller than ListView height, scrollbar is always visible and it's height is equal to ListView height, doesn't matter that policy: ScrollBar.AsNeeded is set. If contentHeight is bigger than ListView height, everything works fine. If ScrollBar is not customized, everything works fine too.

import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    id: window
    visible: true
    width: 640
    height: 480

    ListView {
        id: myListView
        width: 200
        height: 100
        model: 1
        spacing: 5

        delegate: Rectangle {
            width: 200
            height: 20
            color: "red"

            Text {
                anchors.centerIn: parent
                text: index
                color: "white"
            }
        }

        ScrollBar.vertical: ScrollBar {
            id: scrollBar
            policy: ScrollBar.AsNeeded

            contentItem: Rectangle {
                implicitWidth: 6
                implicitHeight: 10
                radius: width / 2
                color: scrollBar.pressed ? "#81e889" : "#c2f4c6"
            }
        }
    }
}
