I've tried to set Map.center in 2 different ways:
1.
Map {
    center: QtPositioning.coordinate(55.7512, 37.6175)
    Component.onCompleted: {
        console.log(map.center);
    }
}
The output was:
qml: 0° 0' 0.0", 37° 37' 3.0" E
It looks that assigning coordinates in this way ignores latitude.
2.
 Map {
    center {
        latitude: 55.7512
        longitude: 37.6175
    }
    Component.onCompleted: {
        console.log(map.center);
    }
}
The output was:
qml: 55° 45' 4.3" N, 37° 37' 3.0" E
So assigning coordinates in this way works w/o problems.
