265137 - <em> tag: Firefox will not stop emphasis if there is an alternate code tag, unkown tag, or <b> between the <em> and </em> tags unless the alternate tag ends first.

Status: RESOLVED DUPLICATE of bug 256731

(Core :: DOM: HTML Parser, defect)

Description

[Joseph Peach]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10

IE renders the example page I made the way the coder would expect.  I'm not sure
if the html standard requires tags changes font format to end before the tags
that started before them, but I believe this is a problem of rendering that
should be fixed by checking the rest of the stack for the html tags that are
being closed.

Reproducible: Always
Steps to Reproduce:
1. Check example web page.
2.
3.

Actual Results:  
Rendering is not what expected.

Expected Results:  
Italics should end

I have noticed this on sites like the New York Times and other news sites when
they are including quotes in articles, the entire article is emphasized or
italic when it should not be.

let me note that the html standard requires _nesting the tags properly_ (e.g.
<foo><bar></foo></bar> is invalid)

anyway, -> parser
