Description pflodo 2005-09-18 06:23:12 PDT
User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b4) Gecko/20050906 SUSE/1.4.99-1 Firefox/1.4
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b4) Gecko/20050906 SUSE/1.4.99-1 Firefox/1.4

I have found as part of a website admin screen (that I have used for years with
IE, Mozilla, Firefox) that 1.5 beta has an issue where due to invalid html.
There is an email address in the form DISPLAYNAME <EMAIL@SOMEWHERE> as text
inside the option tag. Firfox 1.5 beta 1 includes text from outside the form tag
in the text of the dropdown inside the form.

The page is not public so I have created a test file showing the error.

Reproducible: Always

Steps to Reproduce:
1. This is a display/behaviour problem, so just load the page.
Actual Results:  
The submit button and also text outside the form tag, is included inside the
The dropdown doesn't work.

Expected Results:  
The use of an email address enclosed in angled brackets inside the <option> tag
is not valid HTML, but all other browser fail this by not rendering the
resulting offending tag, and still leaving a functional dropdown and submit button.

See the same on Windows.  This is probably all, I guess.

Confirming on
Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050913

Not seeing this in Firefox 1.0, so regression.
Can't find a duplicate, so confirming.

Regression window is between 2005-03-17-07 and 2005-03-18-07, suggesting one of
bug 160095, bug 285250, or bug 284587. 
Comment 5 Uri Bernstein (Google) 2005-09-18 07:52:40 PDT
Since this is a regression, and might affect other cases as well, nominating to
block 1.8b5.

Bug 285250 takes the cake here. I'll attach a fix in a second.

This is exactly the same problem as bug 287349, we need to exclude kHeadMisc
too. I don't think there are any more elements like this.

Easy fix

This is a very safe fix (it only affects userdefined tags inside of option
tags) that fixes a bug which could cause a page to be swallowed up by a
malformed option tag.

pflodo, thanks for making such a simple testcase. That really helped me come up
with the fix for this.
