Yes, unfortunately it is this way. A bug or at least badly programmed.
But you can (like me) use a 3rd party solution.
I have "Ultimate Rotation Control" which can reside in the notification panel.
Aside from being configurable, it even allows to force rotation, so that apps which normally only work in one direction can now be rotated. So it's a recommended bonus anyway.
