Just a slight bug with the floating book on the enchantment table. As I got within the radius that it opens, the book was fine. As I got closer, it deflected to face a different angle. The book would flip to either the left or the right based on the direction of the player relative to the block, rotationally (I tested this). Moving between two of the block's opposing corners would result in the book shifting to the right or left side, as well as how drastic the angle becomes. At these corners the drift was negligible. I attached a few pictures of the drift at its worst and of one with me in the corner with no drift, relative to the sunrise if that helps.
