Identically named properties cause drag-and-drop errors and cannot be dragged to the workspace

Steps to reproduce:
1. Create new VFX Graph and open it
2. Open blackboard, add float property using '+' sign
3. Create inline operator float, and convert it to property
4. Select any or both New float property or properties in the blackboard
5. Try dragging them to the Workspace/Canvas, but do not release mouse, observe the console

Actual result: Properties with identical names can be created, drag and drop is broken for identically names properties
Expected result: Properties have unique names

Reproducible with: 6000.6.0a7, 6000.6.0a8
Not reproducible with: 6000.6.0a6

Note: this can be workarounded by renaming property
