  Does not throw a TypeError if buffer is detached on custom constructor and
  `k >= final`. Using same targetType.

  9. Let A be ? TypedArraySpeciesCreate(O, « count »).
  ...
  14. If SameValue(srcType, targetType) is false, then

  15. Else if count > 0, then
    a. Let srcBuffer be the value of O's [[ViewedArrayBuffer]] internal slot.
    b. If IsDetachedBuffer(srcBuffer) is true, throw a TypeError exception.
