/**
 * This event is getting fired after every slot in the newly opened inventory has item data.
 *
 * New inventory data gets first sent as an empty inventory from the server.
 * Item stack slot information is sent afterwards, sometimes with a short delay.
 *
 * This approach is faster than to wait a fix duration after the inventory open packet is detected.
 *
 * Since this logic only works via packets, and the player inventory (pressing E) is client side,
 * this event does not get fired when opening the invenotory via pressingE.
