281426 - box without "position" on stack with "overflow:hidden" ignores own size attributes and styles

Status: RESOLVED INVALID

(Core :: XUL, defect)

Description

[fireweasel]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050207
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050207

When a box without positioning attributes is attached to a stack that has
"overflow:hidden", its width and height is made equal to that of the stack
overriding all sizing attributes and styles, including CSS max-height & max-width.

I can't believe this is what's meant to happen, even in XUL's ludicrous and 
arbitrary sizing model. It certainly doesn't happen when a box is attached to
another box.

Reproducible: Always

Steps to Reproduce:
1.Load attatched testcase
2.Express amazement.
3.Cry.




Same behaviour in current firefox.

Originally we had <stack> which always stretched everything to fit, and
<bulletinboard> which used positioning attributes. Then someone decided to
amalgamate the two and treat positioned stack children as a special case.

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.

I can confirm this. Please change the resolution.

Is this by design after all? XULPlanet also says,
http://www.xulplanet.com/tutorials/xultu/bulletins.html
> The position of a child element may be specified by placing
> two attributes on the element. For the horizontal position,
> use the left attribute and for the vertical position, use the
> top attribute. If you don't put these attributes on a child of
> a stack, the child will stretch to fit the size of the stack.

Workaround: Put top="0" as an attribute.

Yes, this is by design.  Though see bug 346189.
