There are cases where stylesheets are used partially during document load as
you are doing progressive display of a page and the stylesheet comes in as you
are displaying. I have seen things *like* the H1's being the color in the
stylesheet but the text not. This is bad - you shouldn't use the stylesheet
until it's all in.
However, a much easier way to replicate this bug occurs on my homepage:
http://www.fas.harvard.edu/~dbaron/ . You may want to make a local copy of the
page and the preferred stylesheet, but not the alternates to replicate this
(because that's roughly the way it works from here). The existence of
bug 2765 also helps to see this bug in this case. What happens is that the
page is displayed without stylesheets, but if I click on a link before the
stylesheets load, the link turns the active color I give in the preferred
stylesheet, even though the stylesheet has no other effects. (clicking on the
link doesn't work either, but that's another problem...)
I think you need to somehow withhold the sheets from the progressive display
mechanism until they are fully loaded.

A single style sheet is never used until it (and all of its @imports) are fully
loaded.
When a page links multiple sheets, we currently will use each sheet as soon as
its loaded, the we reflow the whole doc again after the last sheet is in.
Perhaps what you're seeing is the effect of different sheets coming in during
the initial reflow. If so, are you suggesting that NO linked sheets apply until
they ALL are in?

Yes. That is, you shouldn't use a stylesheet at all until you've reflowed the
whole document with it. Otherwise things get messy, and possibly illegible (if
the sheet were designed badly, which many are). Fixing bug 2765 will fix the
alternate part, but not the multiple (persistent) stylesheets problem. (I'm
not sure I've seen that, though.)
Perhaps I've only seen this on pages with alternate or multiple SS. That makes
sense.
So I guess you should either reflow each time you get a stylesheet completed or
you shouldn't use them until they're all in. If positions are held on reflow,
then it won't be so bad to reflow more. I think troy (or someone) has a bug on
that.

Using 6/14 Apprunner, style is applied as a whole. Verifying
bug fixed.
