162254 - Hyperlinks shown as plain text

Status: VERIFIED DUPLICATE of bug 58917

(SeaMonkey :: General, defect)

Description

[William Chi]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0rc2)
Gecko/20020512 Netscape/7.0b1
BuildID:    20020512

There are links which fail to be rendered as links. Instead they are just shown
as plain text.

This can be reproduced by using HTML code as described below.

Reproducible: Always
Steps to Reproduce:
1. Create a hyper link.
2. Inside the <a></a> tags open a <font> section
3. Do not close the <font> with a </font>
4. Repeat 1-3 over 200 times.

The section would look like <a href="some link"><font>some text</a>
After 197 such links, further links will fail to be shown as links.

Actual Results:  As explained above, the links after the 197th link fail to be
shown as links.

Expected Results:  Previous version of netscape shwo all links properly.

important reminder : this markup is *totally* invalid anyway... For my personal
perspective, this bug is clearly INVALID or WONTFIX.

Right, and wrong.
Mozilla's Page Source displays the last working link and the next plain text as
the following:
<a href="ref_h-l.htm#91598" _base_target="display">
<font size="-1" face="Helvetica,Arial"> lowsrc
</font></a><font size="-1" face="Helvetica,Arial"><br>
<a href="ref_m-q.htm#175987" _base_target="display">
</a><font size="-1" face="Helvetica,Arial"> Math
<br>
</font>

Note that the a tag is closed before the font declaration. Now, the source of
that part _really_ is the following (confirmed using wget and IE):

<a href="ref_h-l.htm#91598">
<FONT SIZE=-1 FACE="Helvetica,Arial"> lowsrc
</a><BR>
<a href="ref_m-q.htm#175987">
<FONT SIZE=-1 FACE="Helvetica,Arial"> Math
</a><BR>

Looks like Mozilla breaks it itself and lies about the source. Tested using
trunk build 20002080807 on WinXP.

Attachment: Very simple test case

This is a very simple html file I used to confirm the behaviour.

I agree that it is not valid markup and I find it ironic that I found it on a
netscape page. 

However the behaviour is inconsistent, either they should all be links, or none
of them should be, that is why I consider it a bug.

The other thing which is an issue is that rival browsers do not exhibit such
behaviour, and it would be a shame to have to use any other browser so that I
can view that page.
