Description

The split tool applied to a polygon layer with shared boundaries (topology correct) fails in producing new polygons with shared boundary (topology, again, incorrect). So much so, if after splitting a polygon into two I try to rejoin the two parts, they do not merge. As a workaround, I need to reshape the new boundary between the two parts and then merge them. Only then dangles that impeded merging (and that should not be there at all) become visible.
