  Deleting an entry does not break a [[MapData]] List.
info: |
  Map.prototype.delete ( key )

  4. Let entries be the List that is the value of M’s [[MapData]] internal slot.
  5. Repeat for each Record {[[key]], [[value]]} p that is an element of entries,
    a. If p.[[key]] is not empty and SameValueZero(p.[[key]], key) is true, then
      i. Set p.[[key]] to empty.
      ii. Set p.[[value]] to empty.
      iii. Return true.
