title: SAPUI5 creating, but not running preload files
body: <p>I have set up the following bootstap, with data-sap-ui-preload set to "auto"</p>
  
  <pre><code>&lt;!-- Bootstrap the UI5 core library --&gt;
  &lt;script id="sap-ui-bootstrap"
          src="resources/sap-ui-core.js"
          data-sap-ui-libs="sap.m, sap.ushell, sap.collaboration"
          data-sap-ui-theme="sap_bluecrystal"
          data-sap-ui-compatVersion="edge"
          data-sap-ui-preload="auto"
          data-sap-ui-xx-bindingSyntax="complex"
          data-sap-ui-resourceroots='xxxxxxxxxxx'&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>This creates a Component-preload.js file in all of my 3 separate apps.</p>
  
  <p>Unfortunately, when I run it, the files aren't minified, and I can access the controller etc directly.</p>
  
  <p>Has anyone else came across this issue?</p>
