Mozilla seems to go nut if I use negative z-index values.
In the example above the text "Content for z-index: -1" is not displayed at all,
while it works if I use positive values of the index.
Reproducible: Always

-> INVALID
<http://www.w3.org/TR/CSS21/visuren.html#z-index>
> The root element forms the root stacking context.
(In simple words: you position it behind the root element.)

This isn't invalid. The root element is transparent so it shouldn't matter that
it is behind it.
But I think this is a dupe.
