Draw L shape
Draw the line at the joints, so that the resulting image was two rectangles
Select L shape by left click
Tools > Split Area ( CTRL+ALT+S )
Nothing expected happend, but closed way is erased with last created node. Ok try undo and again. Same result, but last added node ( from line that connect joints ) is displayed. When you redo, you can get this error
