[ane-gabriela]

Preconditions:

• Have 3-4 users created on Main wiki
• Have a subwiki created with "Both global and local users are available in the wiki" and the Poll app installed on farm - to be available on Main and subwiki

Steps to reproduce:

1. Access the subwiki as Admin
2. Add the global users in the subwiki
3. Create 2 local users
4. Create a new poll
5. Vote with the global users
6. Log in as the local users and observe the poll

Expected results: The local users are able to see all the voting users.

Actual results: The local users can't see the names of the global users that voted, "$user.name" appears instead.

Note: All the names appear while looking at the Poll as a guest (not loged-in)

Environment: Windows 10, XWiki 9.11 Standard, Polls Application (Pro) 2.0
