Error initializing TabBar/NavBar in landscape orientation

[Conti]

If the TabBar+NavBar are initialized in portrit orientation, everything appears to work normally, and on rotation to landscape view, everything resizes as it should. But if TabBar+NavBar are initialized while in landscape orientation the webview appears to be constrained to what would normally be the portrait size. As soon as you change pages the TabBar is pushed below the limits of the screens display. On rotation to portrait orientation you can sometimes see the TabBar where it should be again, but the webview is even more broken, shifted further left and yet still out of bounds at the bottom due to what I can only describe as extra whitespace from a malformed webview.
