[BUG] gitfs fileserver does not sync to all_saltenvs for remote

Description
When utilizing the all_saltenvs option for a gitfs remote resource, you would expect that the resource would be synced to all environments identified by gitfs specified by file_roots in the master configuration. The resource however is only synced to the base environment.

Setup
The following is the master configuration:

git_pillar_provider: pygit2

fileserver_backend:
  - roots
  - git

gitfs_remotes:
  - https://github.com/saltstack-formulas/vim-formula:
    - all_saltenvs: v0.15.5
    - root: vim
    - mountpoint: salt://vim

file_roots:
  base:
    - /srv/salt/states
  dev:
    - /srv/salt/states

pillar_roots:
  base:
    - /srv/salt/pillar/base
  dev:
    - /srv/salt/pillar/dev
    - /srv/salt/pillar/base

pillar_source_merging_strategy: recurse
pillarenv_from_saltenv: True
top_file_merging_strategy: same

The following is the additional minion configuration:

pillarenv: dev
saltenv: dev

The following is the directory structure of /srv/salt:

[root@lima-salt-master salt]# pwd
/srv/salt
[root@lima-salt-master salt]# tree
.
├── formulas
├── pillar
│   ├── base
│   │   ├── hello
│   │   │   └── world.sls
│   │   ├── nginx
│   │   │   └── init.sls
│   │   └── top.sls -> /srv/salt/pillar/top.sls
│   ├── dev
│   │   └── top.sls -> /srv/salt/pillar/top.sls
│   └── top.sls
└── states
    └── top.sls

7 directories, 6 files

The contents of the states/top.sls:

{{ saltenv }}:
  '*':
    - vim

Please be as specific as possible and give set-up details.

• [X ] VM (lima virtualized instance of Oracle Linux 8 on a MacOS host)

Steps to Reproduce the behavior
The above configuration syncs the vim formula resource to the base environment correctly:

[root@lima-salt-master salt]# salt-run fileserver.file_list
- top.sls
- vim/_mapdata/_mapdata.jinja
- vim/_mapdata/init.sls
- vim/absent.sls
- vim/editor.sls

- vim/init.sls

- vim/nerdtree.sls
- vim/pyflakes.sls
- vim/salt.sls

It does not sync the resource to the dev environment:

[root@lima-salt-master salt]# salt-run fileserver.update
True
[root@lima-salt-master salt]# salt-run fileserver.file_list saltenv=dev
- top.sls

Additional list of the environments on the fileserver:

[root@lima-salt-master salt]# salt-run fileserver.envs
- base
- dev
- v0.14.2
- v0.15.0
- v0.15.1
- v0.15.2
- v0.15.3
- v0.15.4
- v0.15.5

Expected behavior
I would expect that the vim formula also be present within the dev environment.

Reproduce the issue with the shown master and minion configuration, then compare salt-run fileserver.file_list for the base and dev environments after salt-run fileserver.update. Use states/top.sls, the gitfs_remotes settings, and fileserver.envs output to trace the environment mapping. Done means the vim formula appears in the dev file list as well as base.
