The selected block when sneaking is shifted

When sneaking, the position of the center cursor and the actually selected block are misaligned.

For example, if you aim at the side of a slab, it will stick to the top of the slab. If you attach a hopper aiming at the side of the comparator, the hopper will attach to the top.
Attached is a picture with highlight enabled, sneaking and pointing the cursor at the wall, and the actual stair block pasted.
