    web-view: fix cppcheck warnings
    
    It found some unused instance member variables, and an extra break. Also
    there is a false-positive warning about an uninitialized return value,
    which is wrong because we always initialize it, but this is easy to
    suppress and it's safer to initialize sooner rather than later anyway.
