Breaking animation on an enchanting table looks weird

Breaking animation on an enchanting table's book looks weird.

Not sure if this is a duplicate of MC-212784 or not, or may be intended.

I included a picture of it, but it doesn't capture the full weirdness of it.

Also, if it is a duplicate, there is no need to remind me to use the search feature, as obviously, I did, I just wasn't sure if this is the same bug or not. Thanks!
