Unfolding diff 1 line below a note inserts diff from first line
If you post a note on a diff line that is **immediately above** a `js-unfold` line (excluding `js-unfold-bottom`) and then click the `js-unfold`, the diff lines inserted will start from the first line of the diff.

This also leads to some odd side effects. (_note the line numbers_)
