With the following code (inserpt from our source code) the first document tag prints to browser as viewable page content. The second one does not. Have tried 2 versions, 1 as is, and the other formatted with <!-- ---...

<td valign="top" class="hotlinks_style">

<!---- HOT LINKS section start ----------------------------------------------->

                <?php ... ?>

<!----- HOT LINKS section end ------------------------------------------------->

                </td>


Reproducible: Sometimes

Steps to Reproduce:
1. Insert the code provided in the details section
2.
3.

<!---- HOT LINKS section start ----------------------------------------------->
 displays on the web page

Expected Results:  
Shouldn't have displayed

The site with this bug had to be updated to clean up the UI, so I can not provide the link. I have posted a copy of the file to http://dev.osmnetworks.net/brad/ffTags.html

The source of that page contains this fragment (which is not an HTML comment):

  <!---- HOT LINKS section start
  ----------------------------------------------->

so it's expected that you see this text in the HTML output.

See also bug 322937 and bug 102127 comment 16 on why you should not use "--" inside HTML comment sections in general.
