If the start and end node of a line are snapped together e.g. a closed loop, the split tool fails to split the line and create two new lines.

To reproduce:
  • Draw a polyline with start and end node snapped together (a loop)
  • Change style of line layer to show start and end nodes on line.
  • Split line using the split tool
  • Start and end point will be moved to the split point but the line will still be whole
  • Drag the start node away from end node and repeat split process.
  • Line will be cut in two as expected
