selector privelege works in webinterface and results in code 403 in nuget clients

Steps to reproduce issue:

1. create a CSEL-selector `selector-foo` for some content
2. create a privilege `prev-foo` for `selector-foo` of type 'Repository Content Selector' with Actions "browse,read" using a nuget repository
3. create a role `role-foo` and give preveleges `prev-foo` and `nx-search-read`
4. create a user `user-foo` and grant role `role-foo`

Expected behavior

User `user-foo` should be able to download nugets by using the webinterface or by using nuget clients.

Observed behaviour

User `user-foo` is able to download nugets by using the webinterface.

User `user-foo` is not able to download nugets by using nuget clients.

Tested nuget clients:

• Visual Studio
• nuget.exe

Nuget clients are getting the error code 403.

What I did to find more information

I gave the preveleges 'nx-repository-view-nuget-read' and 'nx-repository-view-nuget-browse' to the `role-foo` and then user `user-foo` was able to download nugets by using Visual Studio.
