Top Right Inventory Slot GUI glitch using GUI Scale: 4 or Auto and Recipe Book

Description: When starting Minecraft with GUI Scale: Auto or 4 the top right inventory slot is being 'blocked' somehow from mouse access only when the recipe book is open. Dragging an item to the slot results in the item stopping short of the slot and even hovering over the slot does not produce the slot highlight that it's supposed to. The entire slot is not blocked however, only a small portion of the slot in the bottom left corner of the slot can be accessed under these conditions or until the GUI Scale is changed or the Recipe Book closed.
