Current behavior
Javascript error stating: warning.js:36 Warning: Cell: isMounted is deprecated. Instead, make sure to clean up subscriptions and pending requests in componentWillUnmount to prevent memory leaks.

This has been anti-pattern a long time

// Cell.js


setScrollLeft: function setScrollLeft(scrollLeft) {
        var ctrl = this; // flow on windows has an outdated react declaration, once that gets updated, we can remove this
        if (ctrl.isMounted()) { 
          var node = ReactDOM.findDOMNode(this);
          if (node) {
            var transform = 'translate3d(' + scrollLeft + 'px, 0px, 0px)';
            node.style.webkitTransform = transform;
            node.style.transform = transform;
          }
        }
      },

Expected/desired behavior
No error.
