23463	unnecessary.mapcss suggests removing area=yes from railway=platform for indoor features	rskedgell	team	"While area=yes may be unnecessary for most indoor objects, the wiki explicitly requires it for railway=platform - https://wiki.openstreetmap.org/wiki/Tag:railway%3Dplatform

Changing line #24 of unnecessary.mapcss from
way:closed[indoor  ][area?][!highway][indoor!=no]
to
way:closed[indoor  ][area?][!highway][indoor!=no][railway!=platform]
would fix this, but there are probably other cases where area=yes should be preserved.
