[MaximAlien]

Mapbox Navigation SDK version: release-v2.0

Steps to reproduce

1. Create NavigationViewController instance and set NavigationViewController.routeLineTracksTraversal to true.
2. Implement custom route line style using NavigationViewController.navigationViewController(_:routeLineLayerWithIdentifier:sourceIdentifier:)
3. Start active guidance navigation and observe behavior.

Expected behavior

It is expected that route line vanishes based on current progress and retains its style.

Actual behavior

Route line vanishes, but doesn't retain its style.
