[BUG] salt-master - Incorrect ownership of cache files causes gitfs error

Description
We run salt-master as root. After some period of time (seems random), we begin to see 'dubious ownership' errors in /var/log/salt/master:

2025-06-12 19:38:36,229 [salt.utils.gitfs :2897][ERROR   ][3681789] Exception caught while fetching gitfs remote 'ssh://git@instance.com/athing/scripts.git': Cmd('git') failed due to: exit code(128)

When looking at the gitfs cache files complained about in the logs we see they are owned by the salt user instead of root:

[root@salt]# ls -laF /var/cache/salt/master/gitfs/CoHLW+aHiI6cj11mg8+pCMjwYFJBDJlLitI+CFYGgEE=/_
total 0
drwxr-xr-x 3 salt salt  18 Jun 12 19:38 ./
drwxr-xr-x 3 salt salt  15 Jun 12 19:38 ../
drwxr-xr-x 8 salt salt 149 Jun 12 19:39 .git/

Changing the ownership to root:root resolves the issue, but why are the files being created as the salt user when we run as root? This seems to be a 'known' issue, but it has recurred on the same salt-master for us several times over the last few months: https://knowledge.broadcom.com/external/article/378183/salt-master-fails-to-start-with-error-ex.html

Other directories within the cache are owned by the wrong user as well:

[root@salt]# pwd
/var/cache/salt/master

[root@salt]# ls -l
total 16
drwxr-xr-x  4 salt salt   32 Jun 12 17:15 file_lists
drwxr-xr-x 32 salt salt 4096 Jun 12 19:39 gitfs
drwxr-x--- 48 root root 4096 Jun 12 20:16 jobs
drwxr-xr-x 42 salt salt 4096 Jun 12 20:16 minions
drwxr-x---  2 root root    6 Jun 12 13:05 proc
drwxr-x---  2 root root    6 Jun 12 13:05 queues
drwxr-x---  3 salt salt   35 Jun 12 13:05 roots
drwxr-xr-x  2 salt salt   23 Jun 12 19:38 saltapi
drwxr-xr-x  2 salt salt 4096 Jun 12 20:16 sessions
drwxr-x---  2 root root    6 Jun 12 13:05 syndics
drwxr-x---  2 root root    6 Jun 12 13:05 tokens

We have removed the entirety of the cache as a test, and again, after some period of time there is a mismatch of ownership within /var/cache/salt/master.

Setup
Running salt-master on Rocky 8.10 and setting "user: root" in the master config.

Steps to Reproduce the behavior
We aren't sure when this began exactly, but seen it occur on 3006.12, 3007.3, and 3007.4.

Expected behavior
Cache files should be created as the user running salt-master.
