Bug #21316: Namespaces leak with permanent names
https://bugs.ruby-lang.org/issues/21316#change-113199

* Author: fxn (Xavier Noria)
* Status: Open
* Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
Namespaces are not transparent for this program

```ruby
C = Class.new
C.name == 'C'
```

because under a non-main user namespace, the name of `C` has the namespace as a prefix.
