Bug 221972 added logic to place line labels inside the grid when there was not enough space outside of the grid. In that patch, there is a typo for column line label positioning where the line for the label does not extend from the top to the bottom of the column. In practice, this is not noticeable with the current logic, as only the first line will use the line for label placement, and all other columns use only the starting point of the line. None the less, this is currently wrong, and could complicate future fixes that assumed the line was actually a line and not a point in disguise.
