Do bows automatically reload from quiver , but crossbows not?

I’m trying to use a crossbow and automatically reload from the quiver , but can’t do so. I’ve even tested in a test world. Bows can reload automatically with no problem.

Is it a bug or is it a feature ?

That’s how crossbows are irl. You can load one, and get the first shot off faster than an archer can draw an arrow, but after that, they’re more of a headache to reload since you need to brace the crossbow against something to load it.
