When attempting to select a node connection the mouse cursor can change to a text input cursor.
It doesn't harm mouse input but can make selecting a little annoying as it hides the tip of the mouse pointer. It also sends the wrong visual feedback to users.
 
I've not been able to get consistent reproduction steps. At a guess, I would say it's to do with moving the graph or zooming in and out.
 
The funny thing is that nodes with text input don't switch to a cursor icon, they perhaps should.
Steps to reproduce
* Open the attached project with Unity 2020.1 and macOS. 
* Open the EnemyMoveToWayPoints graph
* Select nodes and mousing over thier connections

Notice issue >> Mouse cursor can change to text input.
