Environment
- Mapbox Maps SDK: 11.18.2
- Xcode: 26.3
- iOS: 26.4
- Device: iPad 11 Pro (physical)
- SwiftUI
Observed behavior and steps to reproduce
When using MapViewAnnotation in a SwiftUI Map, annotation positions become incorrect after device rotation when the app window is not full-screen (Split View, Slide Over, or Stage Manager resized window).
The annotations remain at their pre-rotation screen positions instead of being recalculated for the new map projection.
Expected behavior
Annotations should reposition to match their geographic coordinates in the new map projection, just like PolylineAnnotation and other layer-based annotations do.
Notes / preliminary analysis
- Full-screen window + rotation: annotations briefly shift but snap back correctly
- Non-full-screen window + rotation: annotations shift and stay wrong
- Dragging the system window resize handle immediately fixes the positions (annotations snap to correct locations)

Workarounds attempted (none successful):
- proxy.map?.triggerRepaint()
- Camera center nudge and restore
- Zoom nudge and restore
- Viewport reset (.idle then restore)
- .onGeometryChange to detect container size change
