I tested this issue and found that it is related to the orientation of the setup. Some orientations cannot reproduce the bug at all, while other orientations reproduce it consistently.

I’m not convinced this is a bug. Forcing the player’s camera to follow the minecart’s rotation could make it much harder to look around and observe the environment while riding. The current behavior seems more like an intentional design choice that gives players freedom to control their view. A camera lock option or a smoother transition might be a feature request, but I don’t think the current behavior itself is a bug.
