First seven hotbar slots cannot be selected in large inventory interfaces

When entering a large GUI (double chest size confirmed, others possible), the first seven slots of the hotbar cease function. If the player scrolls the mouse over them, the mouse will move, but if one clicks, it does nothing, and the last 'viable' slot still has item information next to it, as if the mouse is still under it. To the extent of my knowledge, it effects all versions, and only started after 1.19 released
