Block break reach inconsistent at certain angles

At certain angles, the mining reach "changes" as the player walks forwards/backwards, causing the player to accidentally break more blocks below/above them than intended.

To reproduce:

See the video attached. At specific angles up/down/left/right, the game may show that the player is unable to reach the block below/above, but as the player gets closer to the block horizontally, the block can be broken, despite the diagonal distance from the eye level to the floor/wall surface being the same.

Expected results

The block break reach should not change at these angles as the player walks forwards/backwards.
