Finding anterior train in invalid date

[Arthur-Lefebvre]

Enregistrement.2025-03-06.113718.mp4

In LMR, when you're searching for an anterior train, you can enter manually an invalid date. A red sign shows but you can still search for it. It seems to find paths in the first valid date of the period.

For the posterior train, you can still do the search but it semms not to find any train when you enter an invalid date.

What did you expect to happen?

I would not be able to search for trains in invalid dates.

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

1. Go to LMR
2. Search for an anterior train in the first date of the period
3. Enter another date manually, outside of the period
4. Search for the same train
