Steps to reproduce
Open up your F3 debug screen
Look carefully at your y-rotation, and make sure it is BELOW 0 (for example straight up is -90), then open your creative inventory (or survival inventory, just make sure there are items there)
Now repeat this but with your rotation ABOVE 0
Notice the difference?
I recommend look straight up/down to make results more reliable
