Refer to the second problem mentioned in Bug# 6749.

The parser is incorrectly parsing CDATA blocks. CDATA blocks should not be
parsed (otherwise they would be called PCDATA blocks). The only thing that
should be recognised in CDATA blocks is ETAGO, i.e.: "</". Markup declarations,
elements, entities (I think) and so on, should not be recognised.

Currently, the following:

   <STYLE type="text/x-dwim-styles">
       make arrow heads look like '<!--'.
   </STYLE>

...turns the rest of the document into a comment, when it should not.

See the test page:
   http://www.bath.ac.uk/%7Epy8ieh/internet/projects/mozilla/viewsource.html
...which demonstrates these problems in terms of what happens in View Source.

Note that this problem is very serious, since it prevents the rest of the
document from being displayed at all.

Lots of subleties involved in tackling this bug.  Need more time to resolve :(

Moving to M10.

Fix is in. Treating <SCRIPT> as pure CDATA section.  The above URL should be
visible now :)   Marking bug fixed.
