Happens in both main hand and off-hand
Just hold a shield and right click to 'block'
Attached below is a resource pack that can show a fix using item rendering translations, and shows images of what the new blocking animation would look like in third person mode.

Confirmed, but how other should the player hold the shield in front without hands and fingers ?

With the arm, like when it's not in use. Either way, it looks wierd

Yes, but that's what the game is doing!

Just like weapons, tools, torches and other items.

One way to fix it is to change the translation & rotation to fit with current hand motion when blocking. Another way is to change the current hand motion to fit with current shield block. Resource Pack included
