Input box ignoring first input.

After sending a message (hit enter) the first input using a Chinese IME (a couple of Chinese characters input) would be ignored, when I try to input again it’s back to normal.
After it’s back to normal, I tried to clear all text from the input box and I hit Enter again, the input would be ignored once more.

Sometimes there’s the first letter of my input underlined just froze there and the IME doesn’t take letters. (happens when I leave mid-input and come back trying to input more Chinese characters).

• Wasn’t there before the UI update.

• Only happens when trying to type Chinese characters into the box. (for me)

• Not sure if this happens to other languages.
