  If thisArg is a primitive, mapfn is called with a wrapper this-value or the
  global, according to the usual rules of sloppy mode
info: |
  6. If _mapping_ is *true*, then
    a. Let _mappedValue_ be Call(_mapfn_, _thisArg_, « _nextValue_, 𝔽(_k_) »).

  OrdinaryCallBindThis, when _F_.[[ThisMode]] is ~global~, where _F_ is the
  function object:
  6. Else,
    a. If _thisArgument_ is *undefined* or *null*, then
      i. Let _globalEnv_ be _calleeRealm_.[[GlobalEnv]].
      ii. Assert: _globalEnv_ is a Global Environment Record.
      iii. Let _thisValue_ be _globalEnv_.[[GlobalThisValue]].
    b. Else,
      i. Let _thisValue_ be ! ToObject(_thisArgument_).
      ii. NOTE: ToObject produces wrapper objects using _calleeRealm_.
