Enderman Teleport To Glass Blocks And Attack When Not Looked At

So I was going to my enderman farm to recharge my tools when I noticed something was not quite right. The endermen were teleporting out of their cage and onto the glass blocks around the farm. I also noticed that they attack you without you even looking at them. This is on PS5 version 1.19.2 Bedrock.
