I would like to configure issue visibility for a specific role in a project so that users can only see issues if those issues have any type of relation to an issue in another project that the user already has permission to view. All other issue visibility settings should apply normally for the project.

In other words, users should be able to view related issues across projects without gaining access to all other issues in those projects.

It could be a implemented as an additional "issue visibility" setting for a Role.

Example Use Cases

1. Helpdesk and Development: A user in the "Helpdesk" project can only see issues in the "Development" project that are related to Helpdesk issues the user is allowed to view. The user cannot see any other issues in the Development project.
2. Asset Handover and Assets: A user in the "Asset Handover" project can only see issues in the "Assets" project that are related to Asset Handover issues the user is allowed to view. The user cannot see any other issues in the Assets project.
3. Cross-Project Coordination: A user in the "Cross-Project Coordination" project can only see issues in the "IT", "Business Department", and "Purchasing" projects that are related to issues in Cross-Project Coordination that the user is allowed to view. The user cannot see any other issues in the IT, Business Department, or Purchasing projects.
