@polesys How about namespacing that event?

function _openMenu(state) {
        $(window).on('click.speedMenuButton', _clickHandler.bind(state));
        state.videoSpeedControl.el.addClass('open');
    }

    function _closeMenu(state) {
        $(window).off('click.speedMenuButton');
        state.videoSpeedControl.el.removeClass('open');
    }
