qmllint anchors/parent major regression

I tried to move from a1c91787264f6f535b5cf094b57ee53058856df4 (Fri Jun 19) to current dev (3ff1cbd6c071b53ed69bb310434070965246144a) and got major problem.

With a1c91787264f6f535b5cf094b57ee53058856df4 such code doesn't produce any warnings:

import QtQuick 2.15

Rectangle {
    anchors {
        horizontalCenter: parent.horizontalCenter
        verticalCenter: parent.verticalCenter
    }
}

now it reports: "Warning: anchors was not found. Did you add all import paths?"

if change code to (2):

Rectangle {
    anchors.horizontalCenter: parent.horizontalCenter
    anchors.verticalCenter: parent.verticalCenter
}

And after that qmllint remembered that "anchors" normal thing for item,
but "parent" also not good, it starts reporting for (2):

Warning: Property "horizontalCenter" not found on type "program" at /tmp/Test.qml:5:38
anchors.horizontalCenter: parent.horizontalCenter
^^^^^^^^^^^^^^^^
Warning: Property "verticalCenter" not found on type "program" at /tmp/Test.qml:6:36
anchors.verticalCenter: parent.verticalCenter
^^^^^^^^^^^^^^

and only such code have no errors with recent qmllint:

Rectangle {   
    anchors.horizontalCenter: parent
    anchors.verticalCenter: parent
}
