ID 605967 - Nodes jump position when dragging them if Open Node Properties is set to happen with a single-click

Problem summary
Nodes jump position when dragging them if Open Node Properties is set to happen with a single-click
 
 
Customer reported version
Mari 7.1v2
 
 
Steps to reproduce

1. Enter the attached script into the Python Console, which makes the Open Node Properties action happen when a node is left-clicked.
    
2. Drag a node just a little.
    
3. Drag a second node just a little.

 
 
Expected behaviour
The node should move in position just a little.
 
 
Actual behaviour
The node jumps to a different position. 
 
Specifically, it doubles the distance between the first and second nodes. This indicates that Mari believes the cursor is still in the first node.
 
 
Workaround
Unknown.
