    [GStreamer] HTTP source element leaks
    https://bugs.webkit.org/show_bug.cgi?id=266177

    Reviewed by Xabier Rodriguez-Calvar.

    There was a reference cycle between the CachedResourceStreamingClient and WebKitWebSrc. Also,
    sending a new ref of WebKitWebSrc to the main thread during basesrc::unlock was inducing an
    additional leak.
