if an inventory is open and you aim at an entity while having it open and blockhit on (e.g. having shopkeeper open in bedwars) it will freak out and every time you left click in the inventory it will try to blockhit (e.g. open the shopkeeper a second time after closed).
easily replicable, just stand in front of a player (mobs probably work too), open your inventory and left click
or at least not working properly.
