Line numbers overlap text in long files

[almondheil]

Description

In large files (>1000 lines long), the line numbers that appear every ten lines begin to overlap the file text and make it unreadable.

• [x] Can you reproduce the issue?

Steps to reproduce

1. Load a file with many lines (at least 1000) in MarkText
2. Scroll down to line 1000
3. Issues appear when there is text on the same line as one of the line numbers

Expected behavior:

Line numbers are visible next to text, but do not obscure it.

Actual behavior:

Line numbers overlap with text, making both unreadable
