ScrollSpyOnce prop is not working

### Description
The `scrollSpyOnce` prop is not functioning as expected. The animation restarts each time the component comes into the viewport instead of running only once.

### Code Example
```jsx
Intl.NumberFormat(getUserLocale(), {
minimumFractionDigits: 2,
maximumFractionDigits: 2
}).format(num)}
/>{' '}{selectedCurrency}

Observed Behavior
The counter animation starts again and again whenever the component comes into view, despite using the scrollSpyOnce prop.

Expected Behavior
The animation should only run once when the component comes into view for the first time.
