test/staging/built-ins/Object/seal /seal-variable-length-typed-arrays.js looks a bit incorrect

[Constellation]

Object.seal will do [DefinePropertyOrThrow](https://tc39.es/ecma262/#sec-definepropertyorthrow)(O, k, PropertyDescriptor { [[Configurable]]: false }). And it should throw an error for TypedArrays since ii. If Desc has a [[Configurable]] field and Desc.[[Configurable]] is false, return false. But the test is checking it does not throw an error.
