QML/Javascript switch statement doesn't execute multiple lines within a case.

import QtQuick 1.1
Rectangle {
    width: 100
    height: 62
    Component.onCompleted: {
        switch (height) {
        case 62:
            console.log("height starts as " + height);
            height = 55;
            console.log("height ends as " + height);
            break;
        default:
            console.log("default case");
            break;
        }
        //console.log("if this line is uncommented, it causes all statements in the switch() to run.");
    }
}
