According to the CSS working group (per the August 2000 F2F [1]) nested floats 
do not affect the formatting context of the ancestors of the float, and do not
get the outer float to shrink wrap about them. We do this correctly when the
outer float also has text in it ([2][3]), but when a float is directly contained
within another float, we mess up and shrink wrap the inner float.

Nesting floats is not very common. Suggesting delaying until post-mozilla0.9.
Comment 2 User image David Baron :dbaron: ⌚️UTC-8 2001-02-22 03:28:49 PST
This is actually a decision I'd like to revisit in the working group - I'd like
to see the outer floats shrink-wrap.

Accepting, and, due to low-impact, moving to future. Also, adding [FLOAT] to

Reconfirmed using FizzillaCFM/2002070913. The testcase doesn't appear as
described. Setting All/All.

CSS2.1 isn't really any more clear on this issue than previous CSS versions....
What's the current state of the spec on this?
Comment 6 User image Hixie (not reading bugmail) 2003-04-22 14:30:11 PDT
I think the status is dbaron and I mildly disagree. I want to say that floats
are not affected by floats within them (hence my filing this bug); dbaron wants
to say that a root formatting context grows to fit all floats, including floats

The WG should discuss this in the coming months.
Comment 7 User image Boris Zbarsky [:bz] (still a bit busy) 2003-04-22 14:39:55 PDT
OK.  Over to layout:floats; hixie, feel free to take this pending WG discussion....
Comment 8 User image Hixie (not reading bugmail) 2003-09-26 14:19:11 PDT
WG discussion has changed this bug slightly...
Comment 9 User image David Baron :dbaron: ⌚️UTC-8 2003-09-26 14:43:20 PDT
You're right about what we should do, but the spec doesn't require it.  10.3.5
is intentionally vague.
Comment 10 User image Hixie (not reading bugmail) 2003-09-27 07:25:38 PDT
Yes, technically "shrink-to-fit" is not defined, but I'm _reasonably_ sure that 
there's no way what we do can count as "shrink-to-fit"...

Also visible when there's a right float in an abs-pos block.

Created attachment 189864 [details]
floated and absolutely positiond divs containing floats

My testcase shows that the bug is also present when a right-floated block
contains another right-floated block. So any block that is floated or absolutey
positioned and contains a right-floated block will be effected by this problem.

BTW, since fixing this bug would fix the second line of the Acid2 test,
shouldn't this be given more attention once Gecko 1.8 is branched?

(This is my first contribution to Bugzilla, so let me know if I did something

According to dbaron this is fixed on his REFLOW branch.
Comment 14 User image David Baron :dbaron: ⌚️UTC-8 2006-12-08 14:53:58 PST
Fixed on trunk by reflow branch landing.
