inheritance cycle not detected correctly

I build qmllint from 14a3b34906be5b749ebc6b6c1d8f6807fff8fd88 in qtdeclarative.

And for such code:

MyListView.qml

import QtQuick 2.15

MyListView {
        MyMouseArea {}
}

MyMouseArea

import QtQuick 2.11

MouseArea {

    enabled: visible
}

qmllint hangs. Interesting that if remove `MyMouseArea {}` from MyListView.qml qmllint detects inheritance cycle:

/usr/local/qt6_tools/bin/qmllint MyListView.qml
Warning: MyListView.qml: MyListView is part of an inheritance cycle: MyListView -> MyListView

qmllint that I use everyday and that build from a1c91787264f6f535b5cf094b57ee53058856df4 with my patches on top of it (because I can not find any revision later that have no bugs) produces warnings for both cases about inheritance cycle.
