Disappearing MarkerViews on phones with unusual aspect ratio

[LukasPaczos]

Reproducible on Samsung Galaxy S8+. I wasn't able to reproduce it on any phone with 16:9.

• To make a marker disappear you have to tilt camera more than 55 degrees and find specific zoom level.
• It unfortunately isn't consistent. When there are many different markers visible at the same time some might disappear and others won't.
• Markers seem to start disappearing below center of the screen.

Problem originates in native code because markers are not made invisible, they are actually not returned at all in NativeMapView#queryPointAnnotations() (invoked in AnnotationManager#getMarkersInRect()).

Marker:

mapboxMap.addMarker(new MarkerViewOptions().position(new LatLng(51.015,16)));

Camera position:

//marker visible
D/onCameraIdle: Target: LatLng [latitude=51.01496666711435, longitude=16.000138947282153, altitude=0.0], Zoom:18.214754127766252, Bearing:107.13901185546955, Tilt:59.99999999999999

//marker invisible
D/onCameraIdle: Target: LatLng [latitude=51.014883108383664, longitude=16.000531546911475, altitude=0.0], Zoom:18.214754127766252, Bearing:107.13901185546955, Tilt:59.99999999999999

This is the same issue as with MarkerView animations (noticed this myself in #8799 ). I would advice you to look into migrating to SymbolLayer instead of MarkerViews. Going to close this as a duplicate, thank you @LukasPaczos for testing!

Alright, thanks a lot for looking into this @tobrun! I'm looking forward to full rollout of location layer as well as #9365 to depracate all those Android views.
