specifically this issue occurs when i use chat macros (typing very-fast/instantly)

Expected behavior: minecraft detects 't' has been pushed then immediately puts whatever text is in the input buffer(i assume this is how it works) into the chat/command line

Actual behavior: minecraft detects 't' has been press and opens chat, but fails to input other pressed keys into the chat

Possible reason for bug: minecraft detects 't' has been pressed and opens chat, but does not start inputting text until next frame/tick, discarding all text entered before that point.

To reproduce:

1. Get some macro software or a macro supporting gaming keyboard
2. record a macro for pressing 't', typing something, then pressing enter
3. run macro in-game in minecraft
4. note how the chat opens, but no text is entered

(Workaround - add delay into macro of about 50ms between pressing 't' and typing text, may not be supported by all software, and is annoying to do instead of 'quick macros' which are recorded on-the-fly in-game)
