656873 - When I right-click on a link in a page containing MathML, parts of the page content disappear.

Status: RESOLVED FIXED

(Core :: MathML, defect)

Description

[Sven]

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Build Identifier: Mozilla/5.0 (X11; Linux x86_64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1

This only happens at some pages containing MathML with operators such as /, ], ), and a link. Upon clicking on the link (does not matter whether it's a left-click or a right-click), random parts of the page starting from the MathML operator are no longer displayed. 

This happens to me with Firefox 4.0.1 on Linux, but not with Firefox 3.6.16. It happened with FF 4.0.0 on Windows 7, but no longer with FF 4.0.1 on Windows.
 

Reproducible: Always

Steps to Reproduce:
1. Load attached file in browser.
2. Right-click on the link in the second line.
3. Watch everything after the '/' in '0/0' disappear.

Actual Results:  
Part of the page content disappears.

Expected Results:  
Page content should remain visible.

I will add an attachement with a simple testcase.

Hoping this might have been fixed by bug 605605.
