Ruler in notebook cells should extend to the border of the cell (not just the invisible end of the editor)

[rehmsen]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.90.1
• OS Version: macOS Sonoma 14.5

Steps to Reproduce:

1. Configure a ruler, e.g. with

   "editor.rulers": [
       80
   ]

2. Open a notebook file e.g. /Users/oler/Code/vscode/extensions/vscode-api-tests/testWorkspace/test.ipynb

Actual:

Expected:

The ruler should probably extend to the end of the cell. I think it's because the actual editor is only those two lines, and then there is a status bar with the language. But visually it looks a bit broken because the editor has no bottom boundary, so stopping the ruler there is weird.

Agree that it looks out of place.

Currently the cell status bar is rendered next to the cell editor, maybe we could explore setting a padding bottom in the text editor, and then render the cell status bar on top of the text editor with a higher zindex.
