Subject: [ruby-core:121955] [Ruby Bug#21320] Namespaces leak with constant lookup

Issue #21320 has been reported by fxn (Xavier Noria).

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

* Author: fxn (Xavier Noria)
* Status: Open
* 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.
