Long command block text crash

After using command blocks for a very long /tellraw command I was disconnect from server when playing on singleplayer then after pressing cancel get sent to the multiplayer screen?

What I expected to happen was...:
The command would run (I heard commands could be infinitely long) or in the previous output box in command blocks it would say "Command Too Long"

What actually happened was...:
I was sent to a screen that said "Disconnected by server, Chat message too long" and after pressing cancel got sent to the multiplayer screen even though i was playing on a singleplayer world.

Steps to Reproduce:
1. In a singleplayer world, put this command into a command block(Or another long comand)

/tellraw @a {"text":"<Bartender> What can i do for you?","color":"white","bold":"false","italic":"false","underlined":"false","strikethrough":"false","obfuscated":"false","extra":[{"text":"[Buy drink]","color":"green","bold":"false","italic":"false","underlined":"false","strikethrough":"false","obfuscated":"false","clickEvent":{"action":"run_command","value":"/tellraw @p {text:\"<Bartender> Sure, there you go\"}"},"hoverEvent":{"action":"show_text","value":"Can i get a drink?"}},{"text":" [Nothing]","color":"red","bold":"false","italic":"false","underlined":"false","strikethrough":"false","obfuscated":"false","clickEvent":{"action":"run_command","value":"/tellraw @a {\"text\":\"<Bartender> So your new here?\",\"color\":\"white\",\"bold\":\"false\",\"italic\":\"false\",\"underlined\":\"false\",\"strikethrough\":\"false\",\"obfuscated\":\"false\",\"extra\":[{\"text\":\"[Yes] \",\"color\":\"green\",\"bold\":\"false\",\"italic\":\"false\",\"underlined\":\"false\",\"strikethrough\":\"false\",\"obfuscated\":\"false\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"/tellraw @p {text:\\\"<Bartender> Nice, you should check out the docks\\\"}\"},\"hoverEvent\":{\"action\":\"show_text\",\"value\":\"I just came for a visit\"}},{\"text\":\"[No]\",\"color\":\"red\",\"bold\":\"false\",\"italic\":\"false\",\"underlined\":\"false\",\"strikethrough\":\"false\",\"obfuscated\":\"false\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"/tellraw @p {text:\\\"<Villager> I've never seen you before\\\"}\"},\"hoverEvent\":{\"action\":\"show_text\",\"value\":\"No i just came for a drink\"}}]}"},"hoverEvent":{"action":"show_text","value":"I don't need anything"}}]}

2. Click on Nothing and you sould be disconnected

3. click "Back to Title Screen" and you should end up in the multiplay screen
