+  Same typedArray ctor argument returns a new cloned typedArray
+info: |
+  22.2.4.3 TypedArray ( typedArray )

+  This description applies only if the TypedArray function is called with at
+  least one argument and the Type of the first argument is Object and that
+  object has a [[TypedArrayName]] internal slot.
+
+  ...
+  17. If SameValue(elementType, srcType) is true, then
+    a. Let data be ? CloneArrayBuffer(srcData, srcByteOffset).
+  ...
+  23. Return O.
