+          1. <ins>NOTE: The following steps could be simplified by using ? ValidateTypedArray(_target_, ~seq-cst~, ~write~) and refactoring SetTypedArrayFromTypedArray and SetTypedArrayFromArrayLike to accept the result as input, but that would observably change the calls into user code and thrown error when IsTypedArrayOutOfBounds returns *true* and _offset_ is negative. Regardless, such a change is still worth pursuing if possible.</ins>
           1. Perform ? RequireInternalSlot(_target_, [[TypedArrayName]]).
