Minecart with a chest has no opening or closing animation

The boats in chests are the same as well

And why is this resolved?

Resolution: Works As Intended

Do look further than just the status...

I know it says Works As Intended but Mojang said this was a feature request so does that mean this is INTENTIONAL but if it's requested on Minecraft Feedback it might be changed?

Yes, this report describes behaviour that Mojang considers intended, but that can change in the future. Feel free to create a feedback post.

Thanks MMK
