Summary

We improved the rendering for large code cell (larger than viewport) this month, including two main changes:

• the execution count is always visible (sticky at the bottom) while scrolling
• when the code cell editor is larger than the viewport, we will only render the editor at the maximum height as the viewport

Please test that when you are scrolling in a notebook editor which contains large code cells, the scrolling is good (as if the code cell editor is rendered at full height) and the execution count is rendered at the ideal position.

Steps to Test:

• Open this Jupyter notebook in VS Code https://github.com/rebornix/notebook-testdata/blob/main/largecell.ipynb (or vscode)
• Scroll the notebook
