Maybe translate3d() has better performance than simple position right?

how about this one ?

```
const style = {
//'position': 'static',
'position': 'relative',
'display': 'inline-block',
//'right': this.state.animatedWidth,
'transform': `translate3d(-${this.state.animatedWidth}px, 0px, 0px)`,
'whiteSpace': 'nowrap'
};
```

Start by locating the marquee component's positioning and animation implementation; no file or test is named in the issue. Compare the existing position/right approach with the proposed translate3d style for equivalent behavior and performance, then verify that marquee movement remains correct.
