When entering long JSON text in Minecraft Bedrock Edition (such as commands, add-on files, or configuration fields), the text input field becomes bugged.
If the JSON is long enough, the input box may stop displaying text correctly, scroll incorrectly, lag, or make editing impossible.
This makes it very difficult to write or edit long JSON data directly inside the game.
The issue appears to be related to text length handling or input field rendering in the Bedrock Edition UI.
This issue occurs especially often when using the §l formatting code for bold text in long JSON strings, which causes the input field to break more frequently.
