Commented code is rendered as xml element with expand and collapse

[merajcal]

If any element has html comments (e.g. ) along with some element which is also inside commented code, is rendered as element.
Example

Note: below mention commented line, renders 3 separate words (i.d class="word").

1. first line
2. student element
3. closing comment (i.e.-->)
   Now commented student rendered as element not commented line.
   <school>
   <!-- commented text. This student is not valid
   <student id="1" name="S1"></student>
   -->
   <student id="2" name="S2"></student>
   <student id="3" name="S3"></student>
   </school>

Confirmed. I stripped out comments and newlines before rendering and that reduced the issue. Even so I still get double dot that I can click on to get empty input box. If I click OK, page refreshes.
