Inline component causes stack overflow with QQuickTest (endless recursion)

import QtQuick 2.15
import QtTest 1.0

Item {
    width: 300
    height: 300

    component MyItem : Rectangle {
        width: 100
        height: 100
        color: "red"
    }

    MyItem {

    }

    TestCase {
        name: "my_test_3000"

        function test_case1() {
            compare(1 + 1, 2, "sanity check");
            verify(true);
        }
    }
}
