Display Issue with Expand Macro

In Firefox 3.6 on Windows XP, when the expand macro is utilized, the a (link) styles apply to all elements in the expanded area and in the subsequent contents on a page. This starts with the actual text that is set in the expand macro as the "title" of the expandable section - which acts like a link in the browser.

I've attached two screen shots with a custom CSS applied (which shows the problem more clearly, via a color change). I have removed and tested each link style individually to determine if it is in fact the CSS that is causing the problem but it is not.

This problem does not occur in the same manner in Chrome or IE7 on Windows XP. In those cases, only list items seem to inherit the style of the expandable link. This happens with list content no matter where it appears in the expandable section.
