Spectator mode: Crash when using shift click in containers while closing container

If you are in spectating mode, and open a chest, you cannot remove items, but if you shift click and item at the SAME time as exiting the chest, the minecraft will exit!

It might not work when just shift clicking, but when clicking, shifting and pressing a numper, AND exiting at the same time, it crashes
