This is a known bug, but for couriosity, what does this bug affect in real life?

I see some problems here:

• performance implications due to JSON.parse and JSON.stringify when using many content scopes
• the mentioned functions do not unify when just the order of the fields is switched ({foo, bar} !== {bar, foo}, but it should be considered the same)
• it's probably the wrong place because it does not unify the objects when several roundtrips (with possibly multiple invocations of UserPermissionsService.getContentScopes()) are made.
• This PR already adresses the same problem, however it will target v8.

Could we port the relevant changes to this PR?

The chips in the user permissions admin panel show incorrect numbers.

I'd prefer using uniqWith and isEqual instead.
