           Summary: "disabled" elements are not loaded when enabled
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All

          Priority: P2

<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Press+Start+2P" title="font" disabled>

Marking the element as disabled in the document skips the download on the initial load (which makes sense). However, if we toggle the element later, the resource is not downloaded. To reproduce: http://jsbin.com/3/omulof/2/quiet

It's interesting to note that enable/disable behavior *does work* for sub-resources. Ex: 

<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Press+Start+2P" title="font">
 <script type="text/javascript">
    document.styleSheets.item('slow').disabled = true;
 </script>

The above will result in the load of the stlylesheet, but the linked fonts will not be fetched. However, if we later toggle the stylesheet as enabled, then the sub-resources are loaded: http://jsbin.com/3/omulof/3/quiet

--- Behavior we want:

<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Press+Start+2P" title="font" disabled> 

- Above should not be downloaded on page load.
- If we toggle above stylesheet via JS later, the resource fetch should happen (plus its sub-resources.. @imports, url(), etc)
