Qt Creator gets confused by merged QML imports

This is valid QML, which runs as expected:

import QtQuick 2.0 as Project
import QtMultimedia 5.0 as Project

Project.Rectangle {
    width: 100; height: 50

    Project.Audio {
        source: "music.wav"
        autoPlay: true
    }
}

However, "Project.Rectangle" will be underlined in red, and autocomplete will not work for the Rectangle type.

If the order of the imports is swapped, then "Project.Audio" will have the red underline lose autocomplete functionality.
