421726 - Mathml no longer renders in 3.0

Status: RESOLVED DUPLICATE of bug 363240

(Core :: MathML, defect)

Description

[mtl_2002]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b3) Gecko/2008020513 Firefox/3.0b3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b3) Gecko/2008020513 Firefox/3.0b3

The bulk of the mathml torture test page renders correctly in firefox-2.0 versions.  However, in 3.0b3, there are errors in numbers 13, 14 (size of integral), 18, 19, 21 (size of summation and integral signs), 22, 23, 24.  I would also consider 28 to be rendered incorrectly.  Spacing and stretching appear to be a major common feature of what is wrong.  
If I can figure out how, I will attach images to show how 2.0 and 3.0 render the mathml differently.  

Note:  in 2.0, I switched the order of Times and Symbol fonts in res/mathml.css, to put Times first.



Reproducible: Always

Steps to Reproduce:
1.  Open mathml torture test page in firefox 3.0b3
2.
3.
Actual Results:  
mathml is no longer rendered correctly, even though it was rendered correctly in 2.0

Expected Results:  
mathml should be rendered correctly, as it was in 2.0

Thanks for your detailed bug report :). Too bad you did not take a look at the Beta 3 release notes and/or had not that much luck with searching in the bug database. From release notes:
"# MathML does not render properly in Firefox 3 Beta 3 (bug 324857 and bug 363240)"

I guess the issues you see here are probably covered by those bugs.

any reason not to mark this as duplicate of one of those bugs?

Installing STIX fonts (see bug 412880) will fix many of the issues with stretchy
operators.  Bug 414277 would also help with that as well as the size of summation signs.

Tables in will be rendering better now (Beta 4) but there are several cases
still being resolved (Bug 363240).

What is wrong with 28?  Have you looked at the MathML source?
