490605 - css font-size doesn't work in table in div with a too long comment before <!DOCTYPE ...>

Status: RESOLVED FIXED

(Core :: DOM: HTML Parser, defect)

Description

[mseb56]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2a1pre) Gecko/20090428 Minefield/3.6a1pre
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2a1pre) Gecko/20090428 Minefield/3.6a1pre

In a website I'm making, I include GPL-notices. Geany (=editor) puts these comments above the <!DOCTYPE ...> tag. So far so good.
But if I include two more lines in the comment tag (<!-- -->), Firefox seems to ignore the CSS font-size property for a <table> in a <div> element.
this site works OK: http://ffbug.awardspace.biz/ff_bug.html
this site doesn't: http://ffbug.awardspace.biz/ff_bug2.html
the latter has two more (indented) lines in the <!-- --> tag and the font size in the table is the firefox standard instead of the css-specified 28 px.

Reproducible: Always

Steps to Reproduce:
1. Open the websites noted in the 'Details' section
Actual Results:  
The font size of the text in the table-in-div is standard (14px?) instead of the css-specified 28px (in ff_bug2.html)

Expected Results:  
The font size of the text in the table-in-div should be 28px, what was specified in css. So do Opera and Safari

Tested on clean install on Windows with latest nightly build and on Linux with latest nightly build (no clean install)

The second is using Mozilla Quirks Mode (because a standard DOCTYPE is not found in the first buffer?):

83 table {
84   text-align: start;
85   white-space: normal; /* compatible with IE & spec */
86   line-height: normal;
87 
88   /* Quirk: cut off all font inheritance in tables except for family. */
89   font-size: -moz-initial;
90   font-weight: -moz-initial;
91   font-style: -moz-initial;
92   font-variant: -moz-initial;
93 }

The HTML5 parser seems to handle this correctly (html5.enable set to true)
