@eneiluj seems like an early alternative to your fix in #25879

[chiefbrain]

$state.loaded() is called even if filtered users list is empty. So the empty content message won't be displayed when filtering to show disabled users while there is no disabled users. That's why filteredUsers.length is used to determine if we call $state.loaded() in #25879.

length ist still used in users.js: const usersCount = Object.keys(response.data.ocs.data.users).length.

@chiefbrain As I couldn't push to your branch, I applied your changes to my branch in #25879, rebased on master and resolved the conflicts. I hope you don't mind 😁

@ChristophWurst @skjnldsv #25879 is the same as this PR and it's ready to be merged.
