Why didn't Voldemort become master of the Elder Wand after hitting Harry with the killing curse in the Forbidden Forest?

The explanations that don't work:

1) "Voldemort didn't kill Harry": Draco, Harry, Dumbledore, and Grindelwald all became masters of the Elder Wand without killing its previous master. Also, it's debatable anyway whether Harry died and came back or never actually died, but it doesn't even matter.

2) "Voldemort didn't disarm Harry of the Elder Wand specifically": Harry became master of the Elder Wand by just physically grabbing another wand (not the Elder Wand) out of Draco's hands without even using magic, and not even in the presence of the Elder Wand either. Grindelwald became master of the Elder Wand just by stunning its master at the time while Grindelwald himself held the Elder Wand.

3) "Voldemort didn't disarm Harry": Grindelwald became master of the Elder Wand just by stunning its master, not by disarming him, while Grindelwald himself physically held the Elder Wand. The second master of the Elder Wand just knifed the first owner in his sleep to become its master.

4) "Harry didn't even try to fight Voldemort in that moment, so it doesn't count as a defeat": Dumbledore just willingly let Draco disarm him in the Astronomy Tower for Draco to become master of the Elder Wand.

So, with those explanations excluded, why is it that Voldemort did not become master of the Elder Wand after hitting Harry with the killing curse in the Forbidden Forest?
