[BUG] JetBrains Rider plugin auto-scrolls to bottom even after response is complete

What's Wrong?

In the JetBrains Rider Claude Code plugin, the chat panel automatically
scrolls back to the bottom whenever the user tries to scroll up to read
previous parts of the response — even after the response has fully finished
streaming. This makes it impossible to read long responses without the view
jumping back down.

What Should Happen?

After the response is complete, scrolling up should stay at the scrolled
position without jumping back to the bottom

Additional Information

This occurs in the JetBrains Rider IDE Claude Code plugin.
After a response fully completes, scrolling up in the chat panel causes
the view to immediately jump back to the bottom.
