Research direction
Start with the linked ECharts Sankey minimal reproduction and inspect the Sankey layout path handling layoutIterations: 0. Reproduce the ordering problem with the supplied option and determine what sorting behavior is expected when iterations are disabled; done means the resulting node order is correct in that case.
