240368 - Overflow properties doesn't work with object which are XUL documents

Status: RESOLVED WORKSFORME

(Core :: Web Painting, defect, P2)

Description

[Xanthor Sccas]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7b) Gecko/20040411 Firefox/0.8.0+
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7b) Gecko/20040411 Firefox/0.8.0+

When we embed a XUL document in a XHTML one, with the object tag, and when we
try to specify differents values for the overflow property, it doesn't work.

Reproducible: Always
Steps to Reproduce:
1. Load the URL
2. Compare the first objects with XUL files and the last one with HTML file
Actual Results:  
At first seen, it's like if all XUL objects where with overflow : hidden
But sometimes, when you swith to another tab or another window and come back,
the text of the XUL file is shown even outside the object. 

Expected Results:  
Scrollbars for the auto and scroll properties

I think that this is a regression, because with Mozilla 1.6 and Firebird 0.7 the
scrollbars existed.

(I don't know if I should put this bug in XP toolkit : XUL)

The fact that 'overflow' on the OBJECT or IFRAME is applied to the HTML document
is really a quirk. 'overflow' on the OBJECT element controls what happens if the
child elements of the OBJECT overflow, but the OBJECT doesn't really have
children. It's just "the document". You really need to control this using
'overflow' *inside* the XUL document.

hmm. I take it back. I don't know what's going on here.

Well, per CSS overflow applied to a replaced element means nothing, last I
checked....

No, it applies to replaced elements.

I think this testcase should work as Xanthor expects. I'm actually not sure how
the XUL content escapes from the box in the first place...

The testcase has gone away.
