        * html/HTMLMediaElement.cpp:
        (WebCore::HTMLMediaElement::playbackRate): No need to ask the media engine for the current
            rate, we already have the current value cached.
        (WebCore::HTMLMediaElement::playInternal): Don't reset the engine's playback rate to 
            the default rate.
        (WebCore::HTMLMediaElement::togglePlayState): Do reset the engine's playback rate to 
            the default rate before triggering playback.
