Items swing with the "whack" swing animation type in third person when used from the off hand, regardless of the swing_animation component

With a stab shovel /give @p minecraft:netherite_shovel[minecraft:swing_animation={type:stab}] in the main hand, holding RMB to make paths behaves as expected; the stab animation plays.

But if held in off hand, the stab animation is played in first person view, and whack is used in third person

Also true for hoes, axes and shears. And regardless of how absurd; placing blocks given that animation. placed out of mainhand: stab and stab, offhand: stab and whack.

Expectation is that stab animation plays in 3rd person view regardless of hand.

or that the first and third person view plays the same one.
