- [ ] I am using the latest version of victory-native-xl

Expo

**What platform are you on?** (e.g., iOS, Android)
iOS, Android
### Describe the Problem

**Expected behavior:** The `state.x.position` and `state.y.highTmp.position` should change its value when the `isActive == true`

**Actual behavior:** [What actually happens] The `state.x.position` and `state.y.highTmp.position` is always `0` when `isActive == true`

### Additional Information

This happens when x axis data is a `Date` type

```ts
import * as React from 'react';
import {View} from 'react-native';
import {CartesianChart, Line, useChartPressState} from 'victory-native';
import {Circle} from '@shopify/react-native-skia';
import {type SharedValue} from 'react-native-reanimated';

export function MyChart() {
const {state, isActive} = useChartPressState({x: 0, y: {highTmp: 0}});
const {state: state2, isActive: isActive2} = useChartPressState({
x: 0,
y: {highTmp: 0},
});

return (

{
const date = new Date(value);
const dtString = date.toLocaleString('pt-BR', { month: 'short', day: 'short' });

return Number.isNaN(date.getTime())
? ''
: capitalizeString(dtString.replace('.', ''));
},}}>
chartPressState={[state, state2]}
>
{({points}) => (
<>

{isActive && (

)}
{isActive2 && (

)}

)}


);
}

function ToolTip({x, y}: {x: SharedValue; y: SharedValue}) {
return ;
}

const DATA = Array.from({length: 31}, (_, i) => ({
day: new Date(2024, 11, i + 1),
highTmp: 40 + 30 * Math.random(),
}));
```

Run the provided CartesianChart example with the Date-valued DATA first. Then trace useChartPressState and chartPressState handling in CartesianChart, comparing Date x-axis behavior with numeric x values. Done means state.x.position and state.y.highTmp.position update from 0 while the press state is active.
