QML Map MouseArea::pressAndHold works very improperly

All previous text deleted. The error was caused by mistaken (made by me) field name of coordinate field - longtitude instead of longitude:

                var pos = mMap.toCoordinate(Qt.point(mouse.x, mouse.y))
                console.warn(pos, pos.latitude, pos.longtitude) //<----

But... No any error or warning message appeared in console! Even QtCreator did not mark this as error.
