description: >
  Returns true when deleting any property if buffer is detached
  (honoring the Realm of the current execution context)
info: |
  [[Delete]] (P)

  ...
  Assert: IsPropertyKey(P) is true.
  Assert: O is an Integer-Indexed exotic object.
  If Type(P) is String, then
    Let numericIndex be ! CanonicalNumericIndexString(P).
    If numericIndex is not undefined, then
      If IsDetachedBuffer(O.[[ViewedArrayBuffer]]) is true, return true.
