### Platform(s)

- iOS

### Current Behavior

After locking the orientation
```typescript
await ScreenOrientation.lock({orientation: "portrait-primary"})
```
the `screenOrientationChange` listener still reports changed orientations when the device is rotated as if the orientation was not locked. Calling
```typescript
const {type} = await ScreenOrientation.orientation()
```
also returns the orientation as if the screen orientation was not locked.

The document orientation itself is locked correctly though, no matter how the device is rotated.

### Expected Behavior

The `screenOrientationChange` listener should only report changes when the screen orientation is actually changed, not when the device is rotated while the screen orientation is locked. Likewise `ScreenOrientation.orientation()` should return the correct screen orientation when it is locked, no matter how the device is rotated.

This does not seem to be an issue on Android. There the `screenOrientationChange` listener gets only called after `ScreenOrientation.lock()` if it actually changed the screen orientation. `ScreenOrientation.orientation()` also returns the correct screen orientation after `ScreenOrientation.lock()` was called.
