Current behavior

The /v2/matrix/{profile} endpoint returns an implausibly short distance for one
direction of a route when avoid_features: ["ferries"] is specified, suggesting
a ferry segment is being used despite the avoidance. The same source/destination
pair, queried in the opposite direction, returns the correct long land route.
The /v2/directions/{profile} endpoint with identical parameters correctly
avoids the ferry in both directions.

• ORS version: 9.8.0 (Docker image openrouteservice/openrouteservice:v9.8.0)
• Profile: driving-hgv
• OSM data: Victoria, Australia (victoria-latest.osm.pbf)
• Core preparation enabled with lmsets: ferries

Expected behavior

Both directions should be approximately 205 km, ~3.9 h - the land route via
Melbourne. The ferry has been excluded so the only possible truck route is
around the bay.
