I'm facing another bug introduced in Pivot 2.0.1 which wasn't in 2.0. It's design issue of corner in TabPane with tabOrientation:'vertical'. It's impossible to have content of the corner vertically aligned at the top in TabPane which has tab orientation vertical. In version 2.0 it was possible to align it at the top, center and bottom but in version 2.0.1 it is always at the bottom. It seems that BoxPane in corner has only minimal space.
TabPane with horizontal tab orientation has still the same correct behaviour in 2.0 and 2.0.1 so it's problem only with vertically oriented TabPane.
I attach example application.
