275179 - Shrink-to-fit abs.pos. is too narrow when preferred width > available width

Status: RESOLVED FIXED

(Core :: Layout: Positioned, defect)

Description

[Mats Palmgren (inactive)]

Shrink-to-fit abs.pos. is too narrow when preferred width > available width.
That is, when the shrink-to-fit width == avaialable width, according to
CSS2.1 chap 10.3.7:
http://www.w3.org/TR/CSS21/visudet.html#abs-non-replaced-width

This is the remaining case from bug 201897.
See also the corresponding bug for floats, bug 268499.

Attachment: Testcase

I'm attaching an example that looks like this bug.  But as I understand it this
bug is not new, while my example worked in FF1.0.  Maybe some other regression
related to bug 201897's fix then?  This is a :hover pop-up menu.  In 1.8b1 The
menu that pops up is constrained to be no wider than its parent, the menubutton
that you hover over.  Previously (FF1.0) it was as wide as it needed to be.

Testcase

This testcase is unrelated to this bug and it's rendered correctly.
The reason the "popup menu" is not wider is that the available
width is the width of the <li class="b"> which has the width of
the word "Edit".

URL is the testcase.  I'm not sure if it's already included in the layout regression tests or not.
