Vanilla animations lose animation when item is in off hand

[spaghettube]

The vanilla hitting, eating and shield blocking animation do not play when an item is in the off hand. I have not tested without "default.json" which applies animations to all items that dont already have a set animation.

Here you can see that whenever i have an item in my off hand and no item in the main hand, no animation is played

Here's a similar example, this time with the eating and shield blocking animation, note that in this video I didn't let go of the inspect button, I was only spamming the RMB and the off hand keybind
