Graph Toolkit nodes are not movable when dragging after double-click them

Steps to reproduce:

1. Open the "ETtesting.zip" project
2. Open the "New Graph" graph
3. Instantiate any node in the graph
4. Double-click + hold + drag the node
5. Observe the graph

Actual results: The node stays in the same place

Expected results: The node follows the mouse movement

Reproducible with versions: 0.1.0-exp.1 (6000.3.0a2), 6000.3.12f1, 6000.4.2f1, 6000.5.0b2, 6000.6.0a2

Tested on (OS): Windows 11 Pro (25H2)

Notes:

• Single-click + hold + drag works fine
