On iPhone Duo devices, UITabBarController can display up to 8 tabs under iOS 27.1, while the maximum is limited to only 5 tabs starting from iOS 27.3. Is this a bug? Is there a way to show more than 5 tabs on iOS 27.3?

As demonstrated in the second screenshot, the reported interface orientation is Landscape‑Left, rather than Portrait. Could this be a bug?
