Player doesn't re-sneak automatically if they were sneaking before opening a GUI with Sneak Toggle set

Players now need to manually sneak again after opening a GUI even if they were sneaking before with Sneak Toggle set. Even with the fix of MC-163218 , it doesn’t necessarily mean that the player should remain standing after closing the menu as the sneak button was never pressed.

Steps to Reproduce:
1) Sneak set to toggle
2) Start sneaking
3) Open and then close your inventory (you will stand with the GUI open as intended due to the fix of the mentioned bug)
4) You will remain standing instead of sneaking afterwards
