Can't skip the text anymore after 1.20.30

With the new "update" you guys removed the possibility to quick scroll the text pressing arrows of the controller. Nice because i still can't type a command because of the previous bug added that doesn't allow anyone to see what are they typing on a command block. I guess i have to wait another 4 weeks to see if you guys can fix such an easy problem. Anyway, CAN'T SKIP THE TEXT WHILE TYPING A COMMAND ANYMORE.
