Backward role in relation not honored

[dcesari]

It seems that the "backward" role in relation for one-way cross country piste segments is not honored and these segments are rendered in the opposite direction. For example this segment coincides with a (two way) road originally mapped towards the south but, as a piste, it has the piste:oneway=yes tag and it has a role=backward in the relation, meaning that it can be run one-way towards the north (and this is the case on the field, it's a shortcut for the "Panorama" piste). In my view this is a correct way to tag, but on openskimap.org it is oriented towards the south and this also partly breaks the navigation in the profile.
Could this be fixed?
