420783 - Hiding any of the main menu elements causes a crash

Status: RESOLVED WORKSFORME

(Core :: General, defect)

Description

[Jorge Villalobos [:jorgev] (he/him)]

Reproduced on:

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9b3) Gecko/2008020511 Firefox/3.0b3

Steps to reproduce:
1) Open the DOM Inspector.
2) File > Inspect Chrome Document > [first doc on the list].
3) Select any of the main menu elements (search for id "helpMenu", for example).
4) Set the attribute "hidden" to true (right click on the right pane and select Insert).

This should cause the crash. Setting other attributes (such as label) don't cause the crash. This also happens if you try to set the attribute from an extension script, using .hidden = true.

WFM.  I went through the steps in comment 0.  The menus became hidden, but I didn't see a crash or even an assertion.
