This is deliberate, and was explained in a mail in June:


highway=pedestrian + area=yes will always be over everything else. There's
nothing you can do about it, except make your own renderer :) Or try to
change their minds here:


As for your mapping, If you ask me, it would be better to map sidewalks as
lines tagged with highway=footway. That makes it much easier for routers to
get you to your wanted platform. If you really want to map sidewalk areas,
you can tag them as area:highway=footway. It's currently just a proposed
tag, but I think its philosophy is the best so far for mapping areas of
