If I visualize some json, click-on/select a node, click on "STIX Visualizer" in the top-left corner, and then visualize another (or even the same) valid json, the node that was previously selected still shows up as the selected node.
So, if I visualize 1 json, then try to visualize another json, info for the selected node will be present even if I haven't yet clicked on anything (or even if there are no nodes present).
