Purpose

An improvement allowing the user to drag-&-drop a Note over a Node, pinning it down. Below is the description of the task as set in the brief:

• a. When dragging and hovering a note over a node, border on node appears and release of note will cause note to be pinned to node.
• b. Refer to Added shift + click to nodes and notes to remove from current group #12571 as precedent.

Release Notes

The steps taken to create the new functionality are as follows:

• created the logic inside the StateMachine that handles the case of Note being hovered over a Node
• successfully pins the note when the mouse is released and the note is over the node
• will skip highlighting Nodes that already have a Note pinned (consistent with current behavior to not allow more than 1 pinned Note)
