## Description

[describe the issue here!]
I have 3 database connection in the superset after which I started seeing duplicate permissions.

I investigated the issue and found the root cause. I had added more than two database connections in Superset, which introduced additional permissions. Because of the large number of permissions, pagination was not functioning properly, leading to the duplicate entries being displayed.

After removing the extra database connections, the issue got resolved and everything is working as expected. Can anyone fis this or have a look into it.

No files, tests, or entry points are identified in the issue. Reproduce the problem with three database connections and inspect the permissions pagination behavior; done means duplicate permission entries no longer appear while multiple connections remain configured.
