[Bug 621220] [NEW] buggy HTML comment tag when HTML4 strict

[Yoann FAYOLLE]

Public bug reported:

Binary package hint: firefox

Hello,
I don't know wether I should report this bug to Canonical or to Mozilla, so I'm going to do both.

= System information = 
Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.9.2.8) Gecko/20100723 Ubuntu/10.04 (lucid) Firefox/3.6.8 


= Bug Description =
In an HTML4 strict page, the HTML comment Tag behaves innapropriatelly.

This tag <!-- (lower than, exlamation mark, minus, minus) marks the beginning of a comment
but, if my comment contains -- (twice minus) in the middle of it,
then, the actual end of comment tag (twice minus, greater than) will be skipped -->
And all the text and HTML code following the supposed end of comment will be included into this comment.
The comment will remains opened till the end of a next comment, or till the next comment contains the > (greater than) symbol.

See and test the attached source code.
