As you can see in that image, I can move my cursor to the last line (if I use RET on the last column of the last line), and the last line doesn’t appear on the left line number column.

It is also not highlighted, but as soon as I type on it, like if I enter an “a”, it will be highlighted and appear on the line number list on the left.

This is a very tiny bug, but it slightly annoys me – it really isn’t a major issue, but I’d really like a way to fix it.

Thanks!
