I'm not sure that <span> is allowed within <pre> elements. So the behavior when this occurs may not be well defined. I don't know whether a stylesheet is associated with this page (I didn't go and examine it), nor the effect of your browser's default stylesheet when one is notloaded by the HTML.

What I think should happen is not. I think that JAWS is not allowing line breaks when it sees span within pre elements. In order to attempt to verify that the problem is with JAWS, I want to make sure that span is allowed within the pre element.
