Timeout when editing user info

There are three methods that throw a one minute timeout when trying to edit some user information.
All three are timing out via rest api calls, and setUsername also times out in admin web interface.

There is a check for the timeout function that, in my understanding, should not trigger the timeout if the user who makes the editing has 'edit-other-user-info' privilege, which doesn't seem to work.
I assume it probably has something to do with RocketChat.authz.hasPermission() function/alias, because, for one, I can't access it from browser console.

Operations that result in timeout are:
change name - packages/rocketchat-lib/server/functions/setRealName.js
change email - packages/rocketchat-lib/server/functions/setEmail.js
Here the check is realized like this:
{ 0() { return !Meteor.userId() || !RocketChat.authz.hasPermission(Meteor.userId(), 'edit-other-user-info'); }

change username - packages/rocketchat-lib/server/functions/setUsername.js
In this one the check slightly differs:
{ [0](userId) { return !userId || !RocketChat.authz.hasPermission(userId, 'edit-other-user-info'); }
