+description: Throws a TypeError if comparefn detaches the object buffer
+info: |
+  22.2.3.26 %TypedArray%.prototype.sort ( comparefn )
+
+  When the TypedArray SortCompare abstract operation is called with two
+  arguments x and y, the following steps are taken:
+
+  ...
+  2. If the argument comparefn is not undefined, then
+    a. Let v be ? Call(comparefn, undefined, « x, y »).
+    b. If IsDetachedBuffer(buffer) is true, throw a TypeError exception.
+    ...
