Switch not working in QML code editor

If I edit the file with the following contents:

import QtQuick 2.0
import QtQuick.Controls 1.1

Switch {
    width: 100
    height: 62
}

Switch.qml:5: error: Prototype cycle, the last non-repeated component is 'Switch'. (M303)

Changing the file name to something else then Switch.qml does not solve the issue.
