Unable to navigate to previously sent messages using keyboard arrow keys

(Reported previously under MCPE-174648 but the issue has returned after being fixed. This issue is identical to that one.)

Using arrow keys to navigate to previously sent messages in chat is broken. When you try to do it the text flashes but then immediately disappears. This issue can only be replicated using the keyboard arrow keys, the controller d-pad works fine

Observed result:
Keyboard arrow keys only show the text for a very short amount of time, then it disappears

Expected result:
Arrow keys should correctly navigate through previously sent messages
