If on (re)load the Mozilla window is not wide enough to display the content of
the CSS pseudo-element ":after" for the "body" tag in one single line, the
content is displayed before the actual body part, instead of after.
AFAIK, this concerns only the pseudo-element ":after" for the "body" tag. I
checked the paragraph ("p") tag and everything looked fine to me.
Also, this does not happen if the content of body:after initially fits one line,
and the window is then resized. You'd have to reload the page to observe the
faulty behavior in that case.

Reproducible: Always
Steps to Reproduce:
1. Open the included page in Mozilla Browser
2. If everything looks fine (i.e. the body:after content is displayed after the
actual body part), resize window until the body:after content (without the
actual body part) does not fit on one line anymore
3. Reload

Actual Results:  The body:after content is displayed before the body.

Expected Results:  Display the body:after content after the body.

This pretty reliably WORKSFORME on a CVS tip build on a Linux-kernel OS.
No, I'm still seeing this on Linux.

(worksforme on windows as well unless I'm misunderstanding the testcase)
i tested on the following platform/builds :-
1. linux - branch build as well as trunk build of 2002-10-01
2. win2000 - trunk build 2002-09-30

i am able to reproduce the problem.

steps to reproduce :
--------------------
1. open the testcase attachment 99617 [details] on a maximized window
actual -- body:after content is appended to the actual body part (correct behaviuor)
2. now resize the window so that the content of the ":after" rule does not fit
on one line anymore
3. reload the page 
actual -- body:after content is prepended to  the actual body part
expected -- body:after content should be appended to the actual body part

Seems to have been fixed between 1.4a and 1.4b.
Was fixed between 2003-04-21-12-trunk and 2003-04-21-22-trunk.
I suspect this was fixed by the checkin for bug 145425.
I think it did (based on the addition of IsGeneratedContentFor).  We were
probably thinking the :after content was :before content.

Yeah, maybe....  I've spent some time thinking about this, and I can't quite
figure out what scenario with the old code would have produced this bug (ie what
the order of events would have to be).... so I can't say for sure.  :(
