[Mats Palmgren (inactive)]

Shrink-to-fit float is too narrow when preferred width > available width.
That is, when the shrink-to-fit width == avaialable width, according to
CSS2.1 chap 10.3.5. http://www.w3.org/TR/CSS21/visudet.html#q8

STEPS TO REPRODUCE:
1. load attached testcase

ACTUAL RESULTS:
The float is narrower than the first box.

EXPECTED RESULTS:
The float should have the same width as the first box.

(The abs.pos. case is handled in bug 201897)

(FWIW, I'm not sure it's worth fixing all this stuff before reflow refactoring
-- I'm really hoping to do that soon, and it would probably be more useful to
have your help on the branch once it's started...)

There is a block regression test that also illustrates this:
layout/html/tests/block/bugs/126213-1.html
(when the lower box has more than 1 line of text it should cover the entire
window width)

Bug occurs in Firefox 2006120701 on Linux.
Bug does not occur in Firefox 2006120801 on Linux.

(also verified that layout/html/tests/block/bugs/126213-1.html now works
correctly)

-> FIXED (by the reflow branch landing)

FYI, the testcase could already have been added to the layout regression tests -
I'm not sure.
