Description
## Environment
- Android OS version: 14
- Devices affected: Samsung xcover 6 pro
- Maps SDK Version: 11.7.0
## Observed behavior and steps to reproduce
Certain small polygon features are not rendered on the map when the zoom level is below 16. When zoomed in to a level greater than 16, these features appear as expected. This issue persists despite setting minZoom to a smaller value than 16, and it affects both Android and iOS platforms. Larger polygons render correctly at all zoom levels, so the problem appears specific to smaller polygon features.
## Expected behavior
Features should always be visible if no min zoom is specified.

Research direction
Start by reproducing the issue with the provided style.json and test.geojson on Maps SDK 11.7.0, checking visibility at zoom levels below and above 16. Compare the behavior of the small polygon with the larger polygons and confirm that it renders below zoom 16 when no minZoom is specified.
