Description
## Environment
- Xcode version: 16.2
- iOS version: 18.2
- Devices affected: Any
- Maps SDK Version: 11.13.1
## Observed behavior and steps to reproduce
When I try to zoom in and out all layers I have are blinking.
It actually happened when zoom is changing from 5 to 6, for example when zoom level changes from 5.999 to 6.000 layer always blinks.
It's always happen, 100% reproduce
This issue can be reproduced with [Examples.xcodeproj](https://github.com/mapbox/mapbox-maps-ios/tree/main/Examples.xcodeproj) project (I didn't make any changes).
I've attached a video below (look at the airplane icon):

Research direction
Start with the Examples.xcodeproj project and reproduce the blink while crossing the zoom boundary from 5.999 to 6.000, using the attached video as a reference. Trace the layer rendering behavior during that transition and verify the fix by zooming repeatedly without any layer blinking.
