Others have encountered the same behavior: #1623

But I have other questions：

• Can't clearState. Sometimes throwing errors.
  
• Input and placeholders coincide.
  

I hope to get a solution. Thanks!

I am facing the same issue issue.
when you try to type "안녕하세요" (It's korean)
Its not detected until non-korean char is detected ( ex: space, or alphabet).
I am using Draft JS 0.11.3

Facing the same issue. When you type in composition mode, the state is not updated until you click or add a space:

Is #2094 resolving it?
