What type of PR is this?

• 🐛 Bug Fix

Description

• Fixes Line numbers do not align with lines #286
• Fixes Gutter does not scroll with the code editor #288
• Fixes iOS: Gutter shifted up from the text #261
• Fixes Line Numbers are not aligned with code #250

Line numbers now scroll with the code lines
The padding has been fixed so that

• the line numbers align with the code
• the line numbers cut off at the same point as the code while scrolling

_numberScroll actually already existed and was setup for the scroll syncing so I assume the functionality was lost along the way
