fix: preserve user input when selecting follow-up choices

When users typed a message at a choice prompt and selected a follow-up suggestion,
their typed message was being cleared and lost. This fix preserves the user's input
value after sending the follow-up choice message, ensuring the text area retains
what the user typed.

Fixes #7316
