Crosshair attack indicator does not account for the spear's increased reach

Steps to reproduce: Stand at a distance more than 3 blocks (normal player reach) from an entity, observe the crosshair
Expected result: Crosshair shows the attack indicator that appears when a target is in the player’s reach
Actual result: No changes to the crosshair are made, despite the player being able to hit the entity with the spear having a reach of 4.5 blocks max
