typing while sleeping wil not remember the word you typed

I was playing with some friend the other day. When i went to sleep in minecraft i typed some messages while in bed. When i came out of the bed, and wanted to type something, i pressed the up arrow, the messages were all there, I expected the message that i typed in bed there

But the message i typed while sleeping were not in the list

I tried it multiple times on a vanilla minecraft server, i got the problem every time.

Problem:
Messages you type while in bed will not be remembered by the arrow-up key

Steps to Reproduce:
1. Go to bed
2. Type a message before it will get day
3. Press T
4. Press arrow-up
5. The message typed in bed, will not be in the up-arrow list

It's maybe not that big, but i consider it as a bug, and i reported it here

thanks,
