plot order in spplot with sp.layout

Dear list,

when doing the following, the grid is plotted on top of the sp.layout-item:

data(meuse.grid)
coordinates(meuse.grid)<- ~x+y
gridded(meuse.grid)<- TRUE
data(meuse.riv)
meuse.riv<- SpatialPolygons(list(Polygons(list(Polygon(meuse.riv)), 1)))
spplot(meuse.grid, sp.layout=list("sp.polygons", meuse.riv))

?spplot says:
"for grids and polygons sp.layout is drawn afterwards (so the item will
not be overdrawn by the grid and/or polygon)."

Do I misunderstand the documentation or is this a bug?

Please try:

spplot(meuse.grid, sp.layout=list("sp.polygons", meuse.riv,
   first = FALSE))

I added this now to the spplot documentation.

Thanks!
Tom
