The iOS media controls potentially have two modes: a big play button that sits in the middle of the <video> and inline controls. On devices that allow inline playback, the big play button is always shown and the inline controller is supposed to show once playback begins.
Currently the control type is only checked/changed when readyState changes, so it is possible to get stuck with the overlay button if readyState reaches loadeddata before playback begins.

I wasn't able to come up with a reliable test because the problem this patch fixes is extremely timing dependent.
