Repro steps:
1. Load Yang Visualizer > Select "network" model > Select 1 lvl model depth > Click "network" node in the graph. The detail information of the chosen node is displayed in right panel. Expand right panel.
2. Click child node "network-id" ID 29. The information of the node network-id ID 29 is displayed in right panel together with list of child nodes - "true", "Identifies a network.", "string".
3. Subsequently click each child node ID to display detail information of the selected node.
BUGGY BEHAVIOUR: While info of "true" and "identifies a network" is displayed after clicking the node ID, when clicking the "string" node ID, right panel freezes and no reaction occurs.
EXPECTED BEHAVIOUR: Detail info of each of the selected node is displayed after clicking the node`s ID.
