Vector2 and Vector3 cannot be right-clicked when the variables are in a Shader Graph Material

How to reproduce:
1. Open the attached “material-variant-override-bug.zip“ project
2. Select the “MV_TestShaderGraph” material (Assets/ShaderGraph)
3. Right-click on the “Vector2” or “Vector3” variables

Expected result: It is possible to right-click on the “Vector2” or “Vector3” variables
Actual result: Nothing happens when right-clicking on the “Vector2” or “Vector3” variables

Reproducible with: 2022.3.10f1, 2023.1.14f1, 2023.2.0b10, 2023.3.0a6
Can’t test with: 2021.3.30f1 (The right-click functionality is not implemented)
