Hi,
I have an app with a specific view hierarchy, and when I tested it on an iPhone Duo in landscape, I noticed an issue with how the tab bar is displayed or, rather, how it isn’t displayed.
On iPhone Duo in landscape and on the main screen, the tab bar for a `UITabBarController` pushed onto a `UINavigationController` (itself inside another `UITabBarController`) isn’t visible.
I've tested it in both UIKit and SwiftUI, and the issue is present in both.
I could only get the tab bar to appear by presenting the view modally instead of pushing it, but that isn’t a viable solution for my app.
For example:
```
UIWindow
└─ RootTabBarController (UITabBarController)
└─ UINavigationController (tab 2)
├─ FirstTabViewController (root)
└─ push
└─ NestedTabBarController (UITabBarController)
├─ ItemListViewController (UITableView)
├─ ItemListViewController (UITableView)
└─ ItemListViewController (UITableView)
```
I've put together a simplified [demo repo](https://github.com/janossuta/iphone-duo-issue-demo/tree/main) that shows the problem.
I've attached two images showing that the tabs disappear in landscape mode and are visible in portrait mode.
Can we preserve the original functionality?
