230924 - [MARGIN-C]{inc} Bottom margin not rendered when an initially hidden div is shown in onload function

Status: RESOLVED FIXED

(Core :: Layout: Block and Inline, defect)

Description

[jsp]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7a) Gecko/20040114
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7a) Gecko/20040114

I have a div that I don't want visible unless script is enabled, so I make it
"display: none" by default, then make it visible in my page's onload handler. 
This works just fine, except that the div's bottom margin isn't respected until
the page is reflowed.

Reproducible: Always

Steps to Reproduce:
1. Load the test case.
2. Force the page to reflow (for example, by changing the text zoom, by changing
the browser window width, or by showing or hiding a sidebar).

Actual Results:  
After step 1, there is no white space between the two blocks of text.  After
step 2, there is.

Expected Results:  
The white space between the two text blocks should have been rendered when the
page was initially displayed.

For some reason, the testcase just rendered properly for the first time when I
loaded the attachment.  Reloading it causes it to behave as described.  This
clearly is not just a layout problem.
