title: Invalid alias target location for children topMargin
body: <p>When trying to expose the <code>topMargin</code> as <code>alias</code> in the root component I get the following error:</p>
  
  <pre><code>Invalid alias target location: topMargin
  </code></pre>
  
  <p>The code is the following:</p>
  
  <pre><code>import QtQuick 2.6
  
  Item {
    id: root
  
    property alias textTopMargin: description.anchors.topMargin
  
    Text {
      id: description
    }
  </code></pre>
  
  <p>I can't find any information in the documentation about aliases and anchors, it is forbidden?</p>
  
  <p>EDIT:
  Seem that is caused by this: <a href="https://bugreports.qt.io/browse/QTBUG-65011" rel="nofollow noreferrer">https://bugreports.qt.io/browse/QTBUG-65011</a></p>
