280999 - Nested DIV tags with "display: none" get replicated when "display" changed via javascript

Status: RESOLVED FIXED

(SeaMonkey :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10.1

The uploaded attachment is a series of nested DIV tags with "display: none" set.
As you click on links, a javascript function toggles the next DIV tag
between "none" and "inline".

When you are four DIV tags deep, changing the "display" attribute
of the next DIV tag causes an entire sub-tree of the DIV hierarchy to be
appended (thus appearing twice).

Reproducible: Always

Steps to Reproduce:
1. Open attached HTML page
2. Click on text where instructed


Actual Results:  
A sub-tree of the DIV hierarchy is erroneously replicated and displayed twice.

Expected Results:  
The hierarchy of DIVs should not be duplicated.  Internet Explorer behaves
as I'd expect.

If you look at the attached sample in the DOM inspector, you can easily see
that something is wrong.  The DIV tags are displayed twice in the browser, but
you can only find them once in the DOM inspector.

WFM, 2005-02-02-05 trunk Linux (I do see the bug in 1.7.3 though).

[e-mail], dose it occur if you try a nightly build?
