MapBox variant crashes when using QuickMap

It is possible that this is fixed by https://github.com/microg/android_packages_apps_GmsCore/commit/73fd85a8c7ff2762dd615f3a5caa9d9f1db2b6f5

But just in case it is a different issue, I am getting a crash when using QuickMap. App opens okay (but with map in wrong location). If selecting an area of interest via pull down (e.g. Los Angeles) the app will crash.

OS: LineageOS 14.1 for microG
microG version: GmsCore-v0.2.7.17455-mapbox.apk

Start in MapsActivity.java at zoomToLocation(MapsActivity.java:931) and onConnected(MapsActivity.java:1313), then compare the behavior with commit 73fd85a8c7ff2762dd615f3a5caa9d9f1db2b6f5. Reproduce the QuickMap area-selection flow using the MapBox variant; done means selecting an area such as Los Angeles no longer crashes.
