Inside the position1_loop, I have an asset that is generating the following extra headers:

<link href="/extras/contextMenu/contextMenu.css" rel="stylesheet" type="text/css" />
<script src="/extras/contextMenu/contextMenu.js" type="text/javascript"></script> 

I do not have any extra headers nor is this code in any of my templates. From what I can tell, it is being inserted by the <tmpl_var content> variable inside the position1_loop.

I cannot replicate this behavior on the demo site. Turning on Debugging did not provide any additional information. I need to get to the root of this problem as it is making my site non-XHTML compliant.
