You're right. In that case, it probably makes most sense to use only
railway=crossing and drop the others (as Richard suggested).

The problem here is that pedestrians are routed along the highway=*
way and, as you wrote, tram tracks are usually (unfortunately) mapped
as separate ways. Consequently, the railway=crossing node is
disconnected from the highway=* way with the highway=crossing node
(that is, on another way). Therefore a router doesn't know that trams
also pass this pedestrian crossing (except if pavements and pedestrian
crossings are mapped as separate ways, which, however, has other
drawbacks).
