Description

If you take code from https://bugreports.qt.io/browse/QTBUG-105251

import QtQuick

Window {
    width: 640
    height: 480
    visible: true
    title: 'Resolve my color type'

    Item {
        id: foo

        states: [
            State {
                PropertyChanges {
                    target: foo
                    myColor: Qt.rgba(0.5, 0.5, 0.5, 0.16)
                }
            }        
         ]

        property color myColor: 'black'
    }
}

qmllint reports:

Warning: /var/tmp/Test1.qml:16:30: Property "myColor" is custom-parsed in PropertyChanges. You should phrase this binding as "foo.myColor: Qt.rgba(0.5, ..." [Quick.property-changes-parsed]
                    myColor: Qt.rgba(0.5, 0.5, 0.5, 0.16)
                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

But if this apply suggested fix:

import QtQuick

Window {
    width: 640
    height: 480
    visible: true
    title: 'Resolve my color type'

    Item {
        id: foo

        states: [
            State {
                PropertyChanges {
                    target: foo
                    foo.myColor: Qt.rgba(0.5, 0.5, 0.5, 0.16)
                }
            }        
         ]

        property color myColor: 'black'
    }
}

qmllint reports:

Warning: /var/tmp/Test1.qml:16:21: Unknown property "foo" in PropertyChanges. [Quick.property-changes-parsed]
                    foo.myColor: Qt.rgba(0.5, 0.5, 0.5, 0.16)
                    ^^^

while "qml" uitlity parses the changed qml without any errors.
