Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.77.3
• OS Version: Ubuntu 22.04.2 LTS

Steps to Reproduce:

1. View an extension's readme and scroll to the bottom of it.
2. If the final line of text is long and the body is narrow, the text is obscured by the "return to top" icon.
3. You can't scroll further down to see the text.

Adding some padding to the bottom would be one way to fix it.
