funky tags

I just noticed  some weird color alternation in some of the h3s for the 
web mod transition article, which I think is caused when an anchor 
surrounds only part of the head.

e.g. in http://www.netbeans.org/kb/articles/webModTransition.html
  <h3><a name="Improved">Improved</a> and More Reliable JSP Debugging 
Support</h3> renders the "Improved" as blue and the rest in red.

This seems like a css glitch to me. Why would the question of whether 
something is anchored or not have an impact on its style?
