380646 - Incorrect MathML rendering in an IFrame

Status: RESOLVED DUPLICATE of bug 324857

(Core :: MathML, defect)

Description

[Daniel Hazelton]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a5pre) Gecko/20070514 Minefield/3.0a5pre
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a5pre) Gecko/20070514 Minefield/3.0a5pre

This is apparently a problem with the TeX fonts, as the inline display has a problem with the "delta" symbol, while the IFrame has a problem with everything except the symbol font.

This is definitely a regression, as FireFox 2 does not have these problems.

(This may have already been filed as an addition to the original MathML stress-testing bug, but I did not spot anything about this here)

Reproducible: Always

Steps to Reproduce:
1. Start Minefield build
1. Load Web Page
2. See breakage

Actual Results:  
MathML renders improperly, with the wrong symbols taken from the fonts in use in the IFrame embedding of the MathML demonstration. Another, relatively minor, problem is visible in the "inline" display, where the delta symbol is rendered as the "Symbol Not Found" character (small block with the code inside)

Expected Results:  
Should have correctly rendered the page, as FireFox 2 does.

font.mathfont-family = cmsy10, cmex10, symbol

The first two are the TeX fonts, the last is the symbol font (apparently fully compatible with the Windows symbol font) taken from the typo3 "PDF Generator" plugin. I haven't tested this with the Mathematica fonts, but I am expecting the results to be exactly the same.

I would say this is bug 324857, right?

Comment 3

[Daniel Hazelton]

Yeah - I didn't see that one when looking to see if the bug had already been reported.

Ok, thanks, marking it as a duplicate then.
