If your request relates to additions/features for the react component i.e:
Possibly related... I'll let you move this issue if it is.

Is your feature request related to a problem? Please describe.

• When a node is selected (node 1), click on another node to select it (node 2). This should work as desired.
• When a node is selected (node 1), click on the center top of another node to select it (node 2). The part clicked should be dotted line that is between the node and the node's label. This will not select the node.
• When clicking on empty space (above a node), click the dotted line. It will not prompt to "Add Node/Rectangle"

Describe the solution you'd like

• Clicking anywhere in the node's square should select the node
• Clicking the dotted line should not do anything. This means clicking the dotted line infront of an empty space will prompt the "Add Node/Rectangle" UI
