The way to selecting multiple nodes changes when nodes are inside a container. If nodes are in a container you need to use a modifier key, (shift + drag) to select multiple nodes.

Once you have nodes selected you cannot move them without moving the container. This is a painful UX experience. 

Expected: Drag select functionality should not unexpectedly change.  If you want to move the container and the nodes inside you should click the containers header or introduce a modifier to select the container.

Steps to reproduce

• Create a Bolt class and attach it as a component to a game object
• Create a flow graph
• Add a number of nodes
• Ctrl + Drag select around the nodes to create a container
• Drag select a few of your nodes

Notice issue >> You can no longer drag-select nodes. You need to hold shift +. drag-select.

• Try to move the nodes you drag selected

Notice issue >> When trying to move the selected nodes you move the whole container
