Just to clarify: This has no *real* effect right now, correct? (So it isn't
changing behaviour.) It's just that, on principle, SearchResultContainerViews
should call PreferredSizeChanged() after their update?

Still a bit confused, since it seems like *before* this patch, SRLV::Update()
would not trigger a Layout() in the SRPV, but *after* this patch it will.

Another idea is maybe you should call PreferredSizeChanged() in
SearchResultContainerView::DoUpdate(), rather than manually doing it in all the
child methods?

[calamity, 2014/11/13 03:44:50]

It happened to not be needed before because the SRLV always took up all the
space. Since it has to shrink properly now, the SRPV needs to Layout() to use
the new preferred size of the SRLV.
Ah yeah. GMTA.

Done.
