[REG 6.9 -> 6.10] qmllint: bogus required property warning with generalized grouped property

Consider

import QtQuick

Item {
    id: root
    required property int i

    PropertyChanges {
        root.width: 100
    }
}

This generates a bogus warning:

Warning: test.qml:7:19: Component is missing required property i from here [required]
PropertyChanges{{{}

{}}}^^^^
