How to reproduce

Attached is a 3mf file to slice.

Actual results

By slicing this model you will see that the nozzle makes long travels going from a side of the model to the other even though the Seam Position is set to Nearest.

Here the numbers represent the order of the positions the nozzle travels.

Expected results

Given that the Seam Position is set to Nearest, when the nozzle finishes a wall loop it should go to the nearest wall loop by the shortest travel.
