>>> import HTMLParser
>>> class Parser(HTMLParser.HTMLParser):
	def __init__(self):
		HTMLParser.HTMLParser.__init__
(self)
	def handle_data(self,data):
		print 'DATA: %s' % data
	def handle_comment(self,comment):
		print 'COMMENT: %s' % comment

>>> test3='<STYLE><!-- This is a comment --> 
</STYLE>'
>>> p=Parser()
>>> p.feed(test3)
DATA: <!-- This is a comment -->

Is this a bug?

No, <style> is one of the tags that uses CDATA to make 
comments irrelevant.  This was done so to 'enable legacy 
support' by allowing authors to write:

<style>
<!--
body{dd:00;}
-->
</style>

Without the comments, most legacy browsers would display 
the text "body{dd:00;}" on the rendered webpage.
