AmazonQ skips lines of code without knowledge

## Problem
When asked to generate code, sometimes Q will write the whole program, but would skip out few lines without knowledge. When asked about it, it simply thinks that the code is complete, but the screen does not display it. Even when asked to re-write it will keep skipping the same lines.
Only way to find what is missing is by asking line by line explanation, where you will see the line that is missing with explanations.

## Steps to reproduce the issue
Its incidental and cannot be easily replicated, but I have have seen it more than 10 times out of 30.

1. Go to Q Chat
2. Ask a programming question, preferably a large code
3. Review the code returned to see some lines skipped.
4. Ask to re-write the code and it will keep skipping.
5. For the skipped line, ask Q to explain line by line that code block and it will explain it as if it is there and we cannot just see it.

## Expected behavior
All lines should be there in the codebase..

## System details (run `AWS: About` and/or `Amazon Q: About`)

OS: Linux x64 5.10.227-198.884.### (Mac OS)
Visual Studio Code extension host: 1.87.2
Amazon Q: 1.34.0
node: 18.17.1

Start in the Q Chat flow in the VS Code extension and reproduce the issue with a large programming request, recording the Amazon Q, extension host, Node, and OS versions. Compare the generated response with its displayed code and line-by-line explanation to determine whether lines are omitted from generation or only from display; done means the omission is reliably characterized and verified as fixed.
