Is this behaviour a bug with the experimental material3 features on Android 16?

When the app is portrait mode everything works correctly on Android 15 and 16.

When the app is in landscape mode Android 15 works correctly but Android 16 does not.

e.g. DropMenu on Android 15 Landscape is aligned with the Button

DropMenu on Android 16 Landscape is Not aligned with the Button
