This is a security issue for the customer. An example of this problem is in this HTML code: <!doctype html>
<p><a href="https://www.computerhope.com/"><img src="https://www.computerhope.com/logo.gif"></a></p>
If this is loaded into the viewer, an image from a external site is displayed. He does not want this behavior.
He either wants this feature/bug disabled or he wants to be able to disable this somehow such as in a configuration file
