interval的颜色取不对，总取数组最后一个

- [ ] I have searched the [issues](https://github.com/antvis/f2/issues) of this repository and believe that this is not a duplicate.

### Reproduction link
[https://gw.alipayobjects.com/os/bmw-prod/970b049d-db72-4539-8e56-95ded9958605.txt](https://gw.alipayobjects.com/os/bmw-prod/970b049d-db72-4539-8e56-95ded9958605.txt)

### Steps to reproduce
this.chart.interval().position('x*y').size('x',
() => HDPixelSize(140)).color('x', this.state.data.map(i => i.color))
.style({ radius });
一共绘制两个柱子，但是有时是对的（一个灰色一个蓝色）；但是其他时候只能两个都显示第二个的蓝色

Start with the reproduction link and the interval().position().size().color() call shown in the issue, then trace the interval color handling in F2. Compare cases where the two bars receive different colors with cases where both use the second color; done means the reproduction consistently renders the intended colors for both bars.
