if I have a page:
and i have an anchor within one of the of the accordion sections:
<a href="http://www.example.com/thispage.html"><img src="this_thumbnail.jpg"></a>
this will return true for the default navigationFilter, and cause this accordion section to open when the page loads, regardless of the intialized active state.
As a workaround, since i'm already using the BBQ plugin, i changed the navigationFilter to:
return $(this).attr("href").replace("#","") == $.param.fragment();
this way i'm only comparing the fragment of the href, not the entire href.
a better solution would be to limit the matched anchors to just the head element of the accordion, and not parse the href of all the anchors in the accordion content. if i have 1,000 of links loaded into the accordion, for instance, that's a lot of extra work just to find what the href of the accordion header is.
