Hello.
This PR adds a test case for Array.prototype.unshift returning an abrupt completion in step 4.e.i.
In step 4.e.i, Set(O, ! ToString(j), E, true) is called with
Throwset totrue.So, for
Setto return an abrupt completion, the abstract operation OrdinarySetWithOwnDescriptor must returnfalse.To reproduce this, I used an object with a getter but no setter (
{ get 0() {} }). This ensures the property '0' is read-only, causingOrdinarySetWithOwnDescriptorto returnfalseand triggering theTypeErroras required.
