🐛 [BUG]饼图具有相同的 colorField 的数据，在启用 pie-legend-active 交互时会报 Cannot read properties of undefined (reading 'setMatrix')

### 🐛 Bug description [Please make everyone to understand it]
指定的 colorField 在 data 中有相同的值时，鼠标移入 legend 触发 pie-legend-active 交互则会报错
https://stackblitz.com/edit/vitejs-vite-tonau9rh?file=src%2FPieComponent.tsx

### 📷 Step to reproduce

```
import { useEffect, useRef } from 'react';
import { Pie } from '@antv/g2plot';

export default function PieComponent() {
const ref = useRef(null);
const pie = useRef(null);

useEffect(() => {
const data = [
{ country: 'Asia', year: '1750', value: 502 },
{ country: 'Asia', year: '1800', value: 635 },
{ country: 'Europe', year: '1750', value: 163 },
{ country: 'Europe', year: '1800', value: 203 },
];
if (ref.current) {
const piePlot = new Pie(ref.current, {
appendPadding: 10,
data,
angleField: 'value',
colorField: 'country',
radius: 0.8,
label: {
type: 'outer',
content: '{name} {percentage}',
},
interactions: [
{ type: 'pie-legend-active' },
{ type: 'element-active' },
],
});
piePlot.render();
pie.current = piePlot;
}

return () => {
if (pie.current) {
pie.current.destroy();
pie.current = null;
}
};
}, []);
return

Start with the reproducible example in src/PieComponent.tsx from the linked StackBlitz project, using G2Plot 2.4.33 in Chrome. Reproduce the error by hovering the pie legend with duplicate colorField values, then inspect the pie-legend-active interaction. Done means no setMatrix error occurs and the labels display normally.
