[...]
15. Else if count > 0, then
[...]
e. NOTE: If srcType and targetType are the same, the transfer must be
performed in a manner that preserves the bit-level encoding of the
source data.
f. Let srcByteOffet be the value of O's [[ByteOffset]] internal slot.
g. Let targetByteIndex be A's [[ByteOffset]] internal slot.
h. Let srcByteIndex be (k × elementSize) + srcByteOffet.
i. Let limit be targetByteIndex + count × elementSize.
j. Repeat, while targetByteIndex < limit
i. Let value be GetValueFromBuffer(srcBuffer, srcByteIndex, "Uint8").
ii. Perform SetValueInBuffer(targetBuffer, targetByteIndex, "Uint8",
value).
iii. Increase srcByteIndex by 1.
iv. Increase targetByteIndex by 1.
