When typing a long command, the text of the "Previous Output"-button (an "X" or an "O") is rendered over command suggestions, even if it should be made darker like the button itself.

How to reproduce

1. Make sure "Command suggestions" are enabled
2. Place a command block and enter the command
   "execute if entity @p if entity @p if biome -21 71 23 "
3. The biome suggestions are showing up, the button text "X" or "O" is rendered over the suggestions.
