Cannot navigate past the first previous command in chat history / Cursor jumps to start of line

Since the 1.21.20 update (and continuing in 1.21.21), navigating the previous command history in the chat menu is broken on iPadOS. The system only remembers and retrieves the very last command entered. Attempting to go further back in the history causes the text cursor to jump to the beginning of the text line, instead of cycling to older commands.

This worked correctly in version 1.21.11 and older.

Steps to Reproduce:

1. Open any world in Bedrock Edition (iPadOS).

2. Open the chat and execute a command (e.g., /say One).

1. Open the chat again and execute a second, different command (e.g., /say Two).

1. Open the chat once more and press the "Previous Command" button (Up arrow) on the keyboard to retrieve the last command. (It successfully shows /say Two).

1. Press the "Previous Command" button again to retrieve the older command (/say One).

Observed Results:

Instead of showing /say One, the text in the chat box remains /say Two, and the text cursor simply jumps to the very beginning of the input line.

Expected Results:

Pressing the previous command button repeatedly should cycle backward through the entire recent command history, showing /say One and any other previously entered commands, just as it did in 1.21.11.
