Could you get away w/ passing MediaKeysClient& here instead since I'm assuming
we should never pass a null and m_mediaKeysClientImpl will outlive the page?

Done.

     provideMIDITo(*m_page, m_midiClientProxy.get());
 #if ENABLE(INPUT_SPEECH)
     provideSpeechInputTo(*m_page, m_speechInputClient.get());
