Glaive stalking action anomaly

[Dr-WeiAL]

Minecraft version - 1.19.2
Mod loader - Forge
Mod version - 1.7.1
I am using the latest version available - YES

Describe the bug
I made a Glaive while using the secrets_of_forging_revelations mod, and when it is held in the hand and sneak to switch the shortcut bar, the arm will fall down

To Reproduce
Steps to reproduce the behavior:

1. With Glaive in hand
2. Stalking
3. Switching handheld items

Expected behavior
Look very strange, the arm should not move down

Screenshots or video recordings

Additional context
When I first discovered this problem there was also a problem with arm shaking, but when I updated to the latest version the problem went away, but the arm down problem is still there

After testing, it seems that all two-handed weapons have this problem

I don't think there is anything I can do.
I think this would be down to the PlayerAnimator to fix. Not entirely sure tho.
