Decorator transform puts variables in incorrect scope

[0f-0b]

Describe the bug

If a class is followed by a TypeScript namespace, the decorator transform places variables generated for the class in the namespace.

Input code

class C {
  [Symbol.iterator]() {}
}

namespace NS {
  export function f() {}
}

Config

{
  "jsc": {
    "parser": {
      "syntax": "typescript",
      "decorators": true
    },
    "transform": {
      "decoratorVersion": "2022-03"
    },
    "target": "es2022"
  },
  "isModule": true
}

Expected behavior

_computedKey is declared in the same scope as C.

var _computedKey;
_computedKey = Symbol.iterator;
class C {
    [_computedKey]() {}
}
var NS;
(function(NS) {
    function f() {}
    NS.f = f;
})(NS || (NS = {}));

Actual behavior

_computedKey is declared in the namespace.

_computedKey = Symbol.iterator;
class C {
    [_computedKey]() {}
}
var NS;
(function(NS) {
    var _computedKey;
    function f() {}
    NS.f = f;
})(NS || (NS = {}));
