        New test: LayoutTests/media/video-currentTime-delay.html

        Call invalidateCachedTime() every time one of the cached property dependencies changes,
        i.e. m_paused and m_playbackRate.

        * html/HTMLMediaElement.cpp:
        (WebCore::HTMLMediaElement::prepareForLoad):
        (WebCore::HTMLMediaElement::setReadyState):
        (WebCore::HTMLMediaElement::setPlaybackRate):
