Instance buffer can be detached during loop
info: |
22.2.3.21 %TypedArray%.prototype.reduceRight ( callbackfn [ , initialValue ] )
%TypedArray%.prototype.reduceRight is a distinct function that implements the
same algorithm as Array.prototype.reduceRight as defined in 22.1.3.20 except
that the this object's [[ArrayLength]] internal slot is accessed in place of
performing a [[Get]] of "length".
