Ahmed,
I'm sorry this thread has turned into a political discussion rather than
the technical one it started as. Truth is most everyone here is really
fed up (rightly so) with stubborn people refusing to code to the
standards, so that whenever someone questions those standards we tend to
go berserk. It's all very understandable but often gets in the way of
good discussions.
So on to answering your question.
While I'm not a member of the working group and can't give you a
definitive answer, here are a couple reasons I can think of that the
current standard behavior makes the most sense:
1) This behavior ALLOWS the effect you're seeing. While it may not be
what you want in this case, it's actually a very useful thing to be able
to do. It allows you to "sandwich" in layers between children of the
same element. I ran into a problem in a site I was building the other
day where the easiest way to build it would have needed this kind of
sandwiching. In Moz I was able to bring one (relatively positioned)
child of an element to the top but leave the other child at the bottom,
sandwiching an element from outside in between. In IE both children
were fixed to the same stacking context so I couldn't do this.
2) Consistency: As I pointed out earlier, these context rules directly
parallel the rules for containing blocks in positioning, namely that the
context in which an element's [position, z-index] is calculated depends
on the nearest ancestor with its [position, z-index] specified.
These are just what I can think of off the top of my head. If you want
a more authoritative answer or want to ask about it getting changed, you
might want to bring this up on [EMAIL PROTECTED] after searching the
archives at http://lists.w3.org/Archives/Public/www-style to see if it's
already been brought up.
If you find out anything interesting, please post it back to this
newsgroup so we can all learn.
Regards
