Apple first-person attack animation is incorrect; all attack animations miss final 1-2 frames

Short description of the issue:

All items' attack animations are missing their final 1–2 frames. In addition, items using item format version 1.16.100 and higher have an incorrect attack animation. The vanilla apple (item format version 1.26.30) is one affected example: compared with the golden apple and enchanted golden apple, the apple's attack animation looks visibly wrong.

Steps to reproduce the issue:

1. Hold an apple, a golden apple, and an enchanted golden apple, and compare their attack/swing animations.

2. Observe that the golden apple and enchanted golden apple animations look correct and match each other, while the apple's animation looks strange.

3. Run "/effect @s mining_fatigue 60 50 true" to slow the attack animation.

4. Switch between the golden apple, enchanted golden apple, and apple, and compare the slowed animations.

5. Observe that the golden apple and enchanted golden apple animations overlap with each other, while the apple's animation is clearly different.

6. Observe that the final 1–2 frames of the attack animation are missing for all items, not only for the apple.

Expected result:

All items' attack animations should play completely, including their final 1–2 frames. The apple's attack animation should also match the golden apple and enchanted golden apple animations. Items using item format version 1.16.100+ should not have incorrect attack animations.

Actual result:

All items' attack animations are missing their final 1–2 frames. Additionally, the apple's attack animation is visibly incorrect: when the animation is slowed with Mining Fatigue, the golden apple and enchanted golden apple animations overlap, but the apple's animation does not.
