Can only select GameObject from its back face
Reproduction steps:
1. Open attached project "ObjectSelection.zip", ignore compilation errors, and open scene "SampleScene"
2. In Scene View, click on the top face of "Repro" (original prefab - Assets/Models/Puente Base) GameObject
3. In Scene View, click on the bottom face of the "Repro" GameObject
Expected result: Both of the faces allow to select the GameObject
Actual result: Only the bottom face allows to select the GameObject
Reproducible with: 2019.4.18f1, 2020.2.3f1, 2021.1.0b4, 2021.2.0a3
Could not test with: 2018.4.31f1 (broken assets)
Notes:
1. With Physics Debug 'Collision Geometry' and 'Mouse Select' enabled, both of the faces allow for the GameObject to be selected
2. When used in a new project, the "Repro" GameObject no longer reproduces the issue
3. User only started experiencing problem after encountering "Busy For <...>-s" and "On.MouseDown" dialog window
4. On 2019.4.18f1, only the front face can be used to select the GameObject, rather than the back.

- “Command Line Arguments” window in Hub becomes distorted with long project names
- "Save" button is displayed as active in the Hub "Set project display name" window
- Shader Graph does not get saved when pressing 'File -> Save'
- MultiColumnListView does not visually sort the column when BindingSourceSelection is set to "Auto Assign"
- GameObject assigned to Target Graphic in uGUI Toggle component stays dimmed when replacing it if Interactable was toggled off
Resolution Note (2021.1.X):
The Puente Base model (the mesh referenced by Repro object) does not have a backface. Replacing the shader in Unity with a shader that does backface culling shows this, and I verified using MeshLab that the mesh geometry does not contain double-sided geometry, only the shader setting no culling.
