#2867 — 9.4.4.5 [[Delete]]: Missing ReturnIfAbrupt after step 4


9.4.4.5 [[Delete]] (P):

Add `ReturnIfAbrupt(result)` after step 4, because the default [[Delete]] internal method (9.1.10) calls the specific [[GetOwnProperty]] internal method of an object. And [[GetOwnProperty]] for exotic arguments objects (9.4.4.1) is fallible, so ReturnIfAbrupt should be added.
