* **G2Plot Version**: 2.3.23

Start by running the linked CodeSandbox reproduction at /index.ts with G2Plot 2.3.23 and inspect the radar chart's continuous colorField and lineStyle behavior. Compare the current highlighting for colorField === 100 with the expected result: values 200 and 300 should not also be highlighted.
