Unable to text in chat with Chat Preview On send while sleeping

I can confirm this issue though this report needs some rewording. The problem here is that the "On Send" chat preview option doesn't work while sleeping in a bed. Upon sending your message, it isn't displayed in chat and is instead deleted. Additionally, your typed message is earsed upon waking up contrary to the fix of MC-160710.
