When you look at the chest and you look away, you can still access it if you right click in half a second (or less).
What I expected to happen was:
To place a block.
What actually happend was:
I oppened the chest.
Steps to reproduce:
1. Place the chest.
2. Look at it.
3. Look away and in less then half a sec right click.
I don't know if this is lagg or it is glitch but i tryed 20 times and 15 times it happened. And i just tryed and it also works if you do the same but try to place the block.
You're probably clicking while your cursor is still on the chest but the chest only opens a bit later.
