unable to close the dialogue box when the initator is distant from the NPC

When you are interacting with NPC and away from it (gliding for example) and having pressed any button on the screen, the dialogue box won’t disappear neither can you close the box. 

Only when you exit and rejoin the game, or the npc is outside the loading chunks the dialogue box disappears.

Steps to reproduce:

1. Spawn a NPC

2. Edit the dialogue box of NPC to display buttons that can be clicked

3. Equip elytra and glide towards the NPC

4. (Do not in creative mode) Open the dialogue box while gliding and click the button before the chunk that contains NPC unload

Observed situation:

You cannot close dialogue box via the X on the dialogue box

Expected situation:

You may close dialogue box via the X on the dialogue box
