MapViewportState transitionToOverviewState AnimationDuration has no influence on the animation duration

Nobody has claimed this yet.

## Environment

- Android OS version: 16
- Devices affected: Pixel 6a
- Maps SDK Version: 11.15.2

## Observed behavior and steps to reproduce

Using `MapViewportState.transitionToOverviewState`,
When setting a `OverviewViewportStateOptions`
Parameter animationDurationMs has no influence on the animation duration

## Expected behavior

The animation should follow the parameter animationDurationMs

## Notes / preliminary analysis

The animation duration seems to depend on the distance from the geometry that we want to go on.
It happens when we are to close to the geometry. However, we should still have a smooth animation and not a sort of "jump"

The code :

```kotlin
private fun MapViewportState.toOverview(
cameraModeOverview: CameraMode.Overview
) {
val geometry = MultiPoint
.fromLngLats(Polyline6.decodeToPoints(cameraModeOverview.geometryPolyline6))

transitionToOverviewState(
overviewViewportStateOptions = OverviewViewportStateOptions.Builder()
.geometry(geometry)
.padding(cameraModeOverview.paddingPx?.toEdgeInsets())
.animationDurationMs(DEFAULT_ANIMATION_DURATION) // 600L
.build()
}.build()
)
}
```

Start at MapViewportState.transitionToOverviewState and OverviewViewportStateOptions, then reproduce the behavior with animationDurationMs set while the target geometry is nearby. Trace how the requested duration is handled during the overview transition; done means the configured duration influences the animation and avoids a jump near the geometry.
