Title: Line-highlighter highlights wrong line

The line-highlighter can appear half-way down a line, when there are a lot of lines, or span the whole screen if there is 1 line.
This is a side-effect of turning the editor to `box-sizing : border-box` (my fault).
I've updated the JavaScript to fix the issue.
