When Glow Lichen is placed in this beta it connects to other Glow Lichens hit box to create a full block hit box.
Steps To Reproduce
Step 1: Create the formation in my screenshot with any block or make blocks adjacent to each other.
Step 2: Place glow lichen on the blocks they will make a full block hit box.
Step 3: Look at the Glow Lichen with your crosshair or hit box and you see its a full connected single block and then destroy the connected Glow Lichen.

Observed Results :
When glow lichen is placed they connect to near Glow Lichen with 1 block distance if its adjacent or below and above another placed Glow Lichen then if you aim your crosshair at the Glow Lichen its hit box is a full block.

Expected Results :
Glow Lichens hit box should not connect to nearby Glow Lichen as a full block like Java.
