The block outline of dragon heads is entirely occluded by the block

The bug

The hitbox or block outline of a dragon head is impossible to see because it’s the same size as a normal mob head, even though the dragon head is much larger. This makes it impossible to tell if the block is highlighted or not.

How to reproduce

1. Turn on “high contrast block outlines” in accessibility settings

2. Place a mob head and look at it
   

   

3. Now place a dragon head and look at it
   

   

Expected results

Both blocks should have a visible outline

Observed results

The dragon head does not. If you clip inside the block, you can see that its outline is entirely contained within the model
