Research direction
Reproduce the issue by loading MapboxMaps.MapView onto an iOS view controller without navigation, using MapboxMaps 10.19.0, MapboxNavigation 2.18.4, and MapboxGeocoder.swift 0.15.0. Start by measuring CPU usage during this setup and compare behavior with and without the additional SDKs. Done means the repeatable setup no longer causes excessive CPU usage, lag, or crashes.
