What is the black line around an active cell?
It is a cell border to indicate that the cell is the active cell when it is the only cell selected.

If multiple ranges are selected, then no border appears around the active cell or the any of the selected areas.It is a cell border to indicate that the cell is the active cell when it is the only cell selected.
