733018 - stacking order is incorrect when using an applet or a Flash application in wmode=window, and opacity in other elements

Status: RESOLVED INVALID

(Core :: Layout, defect)

User Agent: Mozilla/5.0 (X11; Linux i686; rv:11.0) Gecko/20100101 Firefox/11.0
Build ID: 20120215222917

Steps to reproduce:

I try to layout some elements on top of an applet.

It seems correct until I use opacity (or rgba, or border-radius) on these elements.

You can have a look to this minimal testcase : http://chatillon.everlong.org/~flash/applet/test-opacity-applet.html

And you can compare on the very same file using an iframe instead of an applet (and which is correct): http://chatillon.everlong.org/~flash/applet/test-opacity-iframe.html

Please note that this is correct in Opera, but not in Google Chrome (which has a different wrong behaviour).

BTW could someone create a testcase with a Flash object instead of a Java applet ?

Thanks !

So that's exactly the same for wmode window (which is the default value IIRC). I'd sort of expected this :)

We're in the process of removing support for plugins (bug 1677160) and bug 1687239 has removed the relevant Layout code, so this bug is irrelevant now.
