Problem
When the user is scrolled up reading older messages and sends a new message, the chat stays in place instead of scrolling to show the sent message.
Expected behavior
Sending a message should always scroll to the bottom so the user can see their message and the response.
Solution
Add an onChange handler for isSending that scrolls to bottom when the user starts sending a message, regardless of current scroll position.
