No. The style methods are called when writing out the <head> section of a
document. Obviously this only happens when the full page is being rendered,
so the issue is that your component isn't returned by #children at that
point. If you know all the components that might be displayed later, you
could possibly return them all from #children but this doesn't work if
you're creating the components on the fly, of course.

I mean, ok, with Ajax you can do whatever you want, so certainly there would
be some way you could add styles to the <head> of the document but you'd
have to write some JS to do it and it seems fairly kludgy.
