    Description

      Running this minimal code

      import QtQuick 2.15
import QtQuick.Controls 2.15

Window {
    id: window
    width: 200
    height: 200
    visible: true

    ScrollBar {}
}

      results in

      Binding on contentItem is not deferred as requested by the DeferredPropertyNames class info because it constitutes a group property.

      The error doesn't seem to affect the actual opacity animation though:

      import QtQuick 2.15
import QtQuick.Controls 2.15

Window {
    id: window
    width: 200
    height: 200
    visible: true

    Flickable {
        anchors.fill: parent
        focus: true
        contentWidth: textItem.implicitWidth
        contentHeight: textItem.implicitHeight

        Keys.onUpPressed: scrollBar.decrease()
        Keys.onDownPressed: scrollBar.increase()

        ScrollBar.vertical: ScrollBar { id: scrollBar }

        Text {
            id: textItem
            text: "ABCDEF\nGHIJK"
            font.pixelSize: 200
        }
    }
}

      ScrollIndicator has the same issue.

      Likely caused by 9fc480db9a02b0f1084719cc676b976efda18013.
