[2.8.0] DataView: expected ArrayBuffer, got Uint8Array

Created by: boris-petrov

This is a regression from 2.7.0:

at new DataView (<anonymous>)                                                                                                                     
at Function.getPSSHData (...)         
at Object.onKeyMessage (...)

I don't have exact lines, I could get them if needed. The error under Firefox is the one in the title, under Chrome is TypeError: First argument to DataView constructor must be an ArrayBuffer.

In this issue there is more information about our usecase (we use Clearkey encryption e.g.) - it hasn't changed since then.

Please tell me if you need more information.
