Description

## Environment

- iOS version: 18.1
- Maps SDK Version: 11.9.2

Point annotations are not added while in the background. Totally unexpected behavior. We migrated from View Annotations and got this behavior. Also there is no API to tell somehow that we have stalled annotations and ask Mapbox to re-sync. We tried layoutMapIfNeeded() and reassigning pointAnnotations array, nothing helped. Clearly we can keep a queue of newly added annotations while in the background, and add them when app becomes active. But I would prefer to understand what Mapbox behavior causes that.

Research direction

The issue names no source files, tests, or entry points. Start by reproducing point-annotation additions while the iOS app is in the background with Maps SDK 11.9.2, then trace the annotation behavior and compare it with View Annotations. Done means explaining the cause and defining a reliable synchronization path.
