Reproduce the curved line example linked in the issue using the provided TypeScript snippet, focusing on the line mark's interaction('elementHighlightByColor', { background: true }) call. Trace that interaction entry point and compare the observed behavior with the two colored series; done means the interaction highlights the intended series in the example.
