Projects saved outside of default folder do not show up in Project Browser on Linux

If a project is saved outside the default Unreal Projects folder or the project folder is moved from Unreal Projects to another location it does not show up in the list of projects on the Project Browser

The projects circled in green in the attached screenshot are inside the Unreal Projects folder and show up in the Project Browser
The projects circled in red are in a different folder on the same computer but do not show up in the Project Browser

1. Create a new project inside the default Unreal Projects folder
2. Save the project and exit the editor
3. Launch the editor to the Project Browser
4. Move the project folder from Unreal Projects to another location
5. Press the refresh button in the Project Browser

Result:
The project is removed from from the Project Browser

Project Browser can detect all projects on the computer regardless of location.
