Bug in get_road_network_mesh function for road markings with type/line definition

[MHoehndorf]

When there is a broken RoadMark with a defined length and space, this only seems to work correctly for the center lane. For lanes +1 and -1 every visible part of the marking starts at the beginning of the road.

This behaviour occurs in https://odrviewer.io/ and also when creating an OBJ using the 'get_road_network_mesh' function.

Sample:
