Gideon's Defeat Damage [Fixed]

Opponent’s Samut, Voice of Dissent attacks
Gideon’s Defeat is triggered
gain 5 life
Gideon’s Defeat is destroyed
Samut, Voice of Dissent (7/8) deals damage to Gishath, Sun’s Avatar (20/20)
Samut, Voice of Dissent is destroyed.

Shouldn’t Samut have been exiled before damage was dealt, or even before life was gained?

I have seen the same kind of bug with settle the wreckage. Attacking creatures are exiled only after they dealt damage.

I saw that in beers and bugs it’s an old bug.

Thank you for the feedback!
