Status: RESOLVED WORKSFORME

(Core :: Layout: Floats, defect, P3)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021109
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021109

In above page, section "Requirements", first paragraph, there's a small N icon,
that when clicked un-hides a div, and when clicked again, hides the div. When
the div is un-hidden, mozilla reflows the objects to display it. When hidding
it, it leaves a white box on the page.

There's similar code later on the same page, that works correctly, ie, reflows
both when un-hidding & hidding their respective divs.

Reproducible: Always

Steps to Reproduce:
1. Visit URL
2. Click on N icon do un-hide div
3. Click again to hide it

Same steps for other icons in the page.

Actual Results:  
Mozilla leaves a white box when hidding the first div, but correctly reflows
when hidding the others.

Expected Results:  
Reflow in all cases

My first bug with new templates on bugzilla got me really confused and frustrated...

Forgot to mention buildid, which is 2002110904 on a linux box.

We need a small test case. This is probably a dupe.

that testcase works fine for me, although that might be because for some reason
it reloads the images each time.

Probably the frame reconstruct isn't marking things dirty the way only a reflow
would.

this should work for you...the same behavior is seen in moz 1.4a & Opera 7.03.
IE6 doesn't even hide the <div>, so it's behavior is even worse. It appears
this could be related to the js...

URL is 404 and only the first testcase is (barely) usable, and it seems
to work as expected (in both pre/post reflow branch landing builds).
Please reopen this bug if you can reproduce the problem in a build dated
2006-12-09 or later.
