* **G2Plot Version**:
* **Platform**:

Run the linked StackBlitz reproduction and start with src/App.tsx, where the bar chart example is configured. Confirm the abnormal scrollbar behavior when color is set through the configuration function, then define the expected scrollbar result before investigating the relevant chart behavior. Done means the reproduction behaves normally with that color configuration.
