Bug #21320: Namespaces leak with constant lookup
https://bugs.ruby-lang.org/issues/21320#change-115534

* Author: fxn (Xavier Noria)
* Status: Open
* Assignee: tagomoris (Satoshi Tagomori)
* Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
The following program

```ruby
X = :top

class C
  X = :super
end

class D < C
  p X
end
```

prints `:super` normally, and `:top` if running under a namespace.
