645634 - css rule :after with 'content' property crashes firefox when applied on <select> [@ nsViewManager::SetViewVisibility ]

Status: RESOLVED WORKSFORME

(Core :: CSS Parsing and Computation, defect)

Description

[Martouf]

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: 4.0

Same bug like:
https://bugzilla.mozilla.org/show_bug.cgi?id=644542
but on another plateform:

The CSS rule :after with the property 'content' will crash Firefox when applied
on <select> element and user click twice on it.

guilty CSS:

    select:after {
        content: ' appended string';
    }


Reproducible: Always

Steps to Reproduce:
1. open attached HTML page
2. click once on <select> to "open" it (nothing happens, it does not open)
3. click a second time, firefox crash
Actual Results:  
Firefox crashes on second click

Expected Results:  
The <select> should open to display options. And I guess the CSS property
'content' should be ignored (at least this is Chrome's behavior)

And that's the crash report on OSX:

I think this is fixed now. Anyone confirm?

Yup, it works fine for me too, on Linux and OSX.
