How to reproduce:
1. Open the attached '1301921.zip' project
2. In the Project window double-click on the 'Test' Asset

Expected result: The 'Test' Asset gets opened in the Graph window
Actual result: The 'Test' Asset does not get opened in the Graph window

Reproducible with: Visual Scripting 1.5.0, 1.5.1-pre.3 (2021.1.0b1)
Cannot test with: Visual Scripting 1.5.0, 1.5.1-pre.3 (2018.4.30f1, 2019.4.17f1, 2020.1.17f1, 2020.2.1f1) (the Visual Scripting package is not supported)

Notes:
- The issue is also reproducible when right-clicking on the Visual Scripting Asset in the Project window and selecting 'Open'
- The issue is not reproducible if the Graph window is already open
