323047 - site with "oncontextmenu='event.cancelBubble=true'" blocks context menu even though it's deactivated in the extended javascript options

Status: RESOLVED DUPLICATE of bug 486990

(Firefox :: Menus, defect)

Description

[Alex]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8) Gecko/20051209 Firefox/1.5 (pigfoot)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8) Gecko/20051209 Firefox/1.5 (pigfoot)

Though in Options - Contents - Javascript extended - "Deactivate or replace the context menu" is not checked, I came across a few sites that can avoid the context menu. If you have many extensions that add context menu entries, the context menu can get very important.

One way to do this is to add oncontextmenu='event.cancelBubble=true' in the body. I have no idea how the other sites did it.

Reproducible: Always

Steps to Reproduce:
1. Visit example site http://home.arcor.de/deckman/context.htm (with Javascript enabled)
2. Right click anywhere on the page
Actual Results:  
Nothing happens.

Expected Results:  
The context menu pops up.

Not even the extension "Allow Right Click" helps.
