iOS: Handheld.PlayFullScreenMovie with FullScreenMovieScalingMode as AspectFill does not scale as expected

I'm trying to play full screen movie on iOS using `Handheld.PlayFullScreenMovie` with `AspectFill` in order to get the movie scaled as the documentation explain that "**Content at the edges of the larger of the two dimensions is clipped so that the other dimension fits the screen exactly. The aspect ratio of the movie is preserved.**" The movie scaled as `AspectFit` NOT `AspectFill`. Anyway, this works on Android as expected. I'm using **Unity 5.3.2f1**. Please give me any suggestion.
