Adding a polyline with a set .linePattern property breaks other polyline annotations inside of the same annotation manager

[crtsajnic-k]

Environment

• Xcode version: 15.4/16.0-beta4
• iOS version: 17.5/18.0
• Devices affected: All
• Maps SDK Version: Checked only on 11.5.2 but probably happens on older versions as well.

Observed behavior and steps to reproduce

Adding a polyline annotation with a set .linePattern property to a polyline manager with existing polyline annotations results in the removal of already added polylines in the annotation manager. Consecutive attempts to add new polyline annotations fail as well.

Expected behavior

Adding a polyline annotation with a set .linePattern property shouldn't affect neither already existing annotations nor disable the addition of new annotations to the polyline annotation manager. Polyline annotations with or without .linePattern property should be able to coexist inside of the same annotation manager.
