33252 - iframe inside a stack widget not masking properly

Status: VERIFIED DUPLICATE of bug 32155

(Core :: XUL, defect, P3)

Description

[andreww]

I created a stack, which the bottom most element contained an <iframe> tag - 
pointing to some website. In other layers of the stack there are elements which 
should, in part, mask some of the contents of the iframe. Instead, the contents 
of the iframe shows 'through' all the way to the top.

Ill be including a test case xul file.

reassigning to evaughan for triage, cc hyatt cuz he sez it scares him to hear

What are you trying to do that necessitates having an iframe inside a stack?  
Window z-ordering? :) Just curious. :)

Why am I putting an iframe in a stack? I may want xul which overlays this 
content in some way, which will be in a higher z-order.

For instance imagine if the sidebar toggled open and closed, but instead of 
pushing the browser's content area over, it simply overlayed it.

Or say I wanted a dockable toolbar which existed as a collapsed tab on the left 
hand side of a document window, and would expand to display tool buttons 
onclick.

The equivalent behavior of the "control strip" in Mac OS.

I encountered this during some testing out of various xul combinations. I have 
no plans for implementing this anywhere in our app ... Prioritize as you see 
fit.
