Missing path item on map for invalid train schedule

[flomonster]

What happened?

When having an invalid path finding train schedule. Path items are not visible on map even if they match a PR.

[!NOTE] I tried with path items using operational_point variant. But it might be the case with other variant such as track_offset, trigram, uic...

What did you expect to happen?

I should see path items on the map.

How can we reproduce it (as minimally and precisely as possible)?

1. Import train_schedules.1.json
2. Edit the "nope" train and go to the "Route" tab
3. We can see the list of path items but nothing on the map

On which environments the bug occurs?

Local

On which browser the bug occurs?
