Status: RESOLVED INCOMPLETE

(Core :: Layout, defect)

Description

[Roger Riche]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4

If you use CSS positioning to display a combination of Java Applet and HTML on top of flash it works fine.  However, if you use javascript to display these blocks for you the HTML block will disappear below the flash movie.

This does not happen on windows platforms.  MacOS Firefox only.  MacOS Safari is fine.

Reproducible: Always

Steps to Reproduce:
1. create a div wrapper with position:relative containing a flash movie.
2. create a div with HTML that is position:absolute;z-index:20;
3. create a div with a containing Applet that is position:absolute;z-index:40;
4. View your results.  Everything is fine.
5. set both absolute divs to display: none;
6. create a javascript function to display these divs.
Actual Results:  
Steps 1-4 will display everything fine.
Steps 5-6 will cause the HTML div to disappear.

Expected Results:  
HTML div should never disappear.

Could you create a standalone testcase for this and attach it to the bug?

I am on my way out of the office but will get a test-case attachment put in early AM. Thanks Adam.

I have setup testcases at the following addresses:

I found that rather than using display:none; method, if I use visibility:hidden then use javascript to visibility:visible I get desired results.

So this works for me on trunk (what will become Firefox 3). [0] Could you test with a trunk build to see if this is fixed for you, too? http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/ You'll probably want to use a new profile to test. See http://kb.mozillazine.org/Profile_Manger for how to create one.

[0] I am seeing a really weird painting bug involving the Java applet, but I'm going to file another bug for that.

I have tested with the lastest trunk and the html block still disappears when the Java applet appears.

Firefox on MacOS 10.4?  in the second testcase at http://www.thinkpod.net/testcase/testcase2.html ?

However, like I said in comment 4, if I dont use display to toggle display of the elements and use visibility instead, I get the desired results.

[Adam Guthrie]

Ah, sorry. I misunderstood the bug. I can reproduce on trunk, too.
