Text input doesn't work in WebView if WebView's ancestor is loaded

import Qt 4.7

Loader {
     width: 360; height: 640;
     Component.onCompleted: { source = "WebTest.qml"; }
}

/*

// This works fine
Rectangle {
    width: 360; height: 640;
    WebTest { }
}
*/

import Qt 4.7
import QtWebKit 1.0


Rectangle{
    anchors.centerIn: parent
    border.width: 3

    width: 240
    height: 360

    WebView {
        id: webView
        anchors.leftMargin: 1
        anchors.topMargin: 1
        anchors.fill: parent
        url: "http://jurpo.org/~elpuri/edits.html"
        opacity: 1
    }
}
