No, it doesn’t give haloform reaction.
It seem like it gives positive haloform test because of
Methyl ketone but in reality it doesn’t give.
Haloform is used to distinguish between acid derivative and methyl ketone.
Actually,it look like that it will give positive iodoform test but in reality it will not give because in this the (CO)-CH3 group are present in form of anhydride,so this is not free to perform iodoform test.
Same case will be found in Ketones sometimes,so always let check what is the compound.
You will easily get your answer.
