During a build I have an init stage followed by a parallel section with 4 stages

init ---|--Linux Release
        -|--Linux Debug
        -|--Windows Release
        -|--Windows Debug

During the build I try to click on a node in the parallel section other than Linux Release the UI doesn't update (Doesn't have to be Linux Release, it's whatever the topmost node displayed in the parallel section is, I reordered the script to test this)
But if I click the "init" node (which is already complete and outside the paralell section) it happily updates the UI (I noticed it basically just adds a number to the end of the URL).

I put some break points into the javascript and found that it's at least getting as far as this bit of code:

        key: 'nodeClicked',
        value: function nodeClicked(node) {
            var stage = node.stage;
            var listener = this.props.onNodeClick;

            if (listener) {
                listener(stage.name, stage.id);
            }

            // Update selection
            this.setState({ selectedStage: stage });

When I manually append the stage.id of a node in the parallel section to the URL and refresh the page then the view updates correctly and I can see the status of the node I had clicked on. (I find the node stage.id by clicking the node I want and hitting a breakpoint I set in the above code and then checking the value of the stage.id)
