Steps:

• Go to a singleplayer world
• Give yourself a timer and 2 different blocks
• Place the timer and open it's gui
• Exchange the two blocks in the inventory
• When you place one of them, it will instantly become the old one
• The issue persists until you relog, and opening any container fixes your inventory, although it will stay out of sync after closing it
