External Guest user not able to view internal project

Summary

As per our documentation, it appears that a Guest External User should be able to view a repository code, however, this is not the case. Perhaps the documentation is not clear

Doc: https://docs.gitlab.com/ee/user/permissions.html#guest-user
External User: https://docs.gitlab.com/ee/user/permissions.html#external-users-permissions

In cases where it is desired that a user has access only to some internal or private projects, there is the option of creating External Users. This feature may be useful when for example a contractor is working on a given project and should only have access to that project.

Steps to reproduce

Add a Guest External User to Internal Project:

Screen_Shot_2019-09-17_at_11.55.30

External Guest User can not View Repository

Screen_Shot_2019-09-17_at_11.56.40

According to the docs above and Project member permissions, this should be possible.

What is the expected correct behavior?

External Guest User should be able to view the repository.
