I upgraded to Webstorm 2016.1 (WebStorm-145.258.3) this morning, and much of the nice React support that was present in the previous version I was using (WebStorm-143.382.36) seems to have been lost. For example, this.state and this.props are both unrecognized in the latest upgrade, as shown below.
You can see the previous version running on the left, and the updated version running on the right. They're both using the same set of preferences, but the updated version is clearly missing some recognition of React.
Was something perhaps missed when importing my preferences, or did something get disabled?
