I can see the hitboxes of mobs through the edges of certain blocks.

Steps to reproduce

1. Place down one of the certain blocks affected by this bug (chests, shulker boxes, beds, signs, hanging signs, decorated pots)

   1. This bug also affects every other block not mentioned if you look at the non-affected block as it’s border overlaps with one of the affected blocks (look below to the screenshots with the oak log as an example of what I mean)

   2. This bug also extends to blocks with borders that have empty space (like lightning rod or an end rod) where the border of the block causes the hitbox of the mob to appear through the mob’s texture as seen in the lightning rod screenshot below

2. Spawn a mob within view of the block (I chose cats in my screenshot examples because they sit still, and it’s how I discovered the bug)

3. Turn on mob hitboxes using F3 + B

4. Highlight the affected blocks by looking at the block with your crosshair in reach of the block

5. You should be seeing the hitboxes through the blocks

Expected behavior

The outline of the block should not reveal hitboxes on the other side and should look like every other block’s outline

Observed behavior

The hitboxes are visible though the edge highlights
