write selectors with vendor prefixes

Hi, how i can write selectors with vendor prefixes? Now I use jss together with [Material UI](https://material-ui.com/), I try to write this code, but it does not work. However, if I write this on vanilla css, the code works fine.

```
input[type="number"]::-webkit-inner-spin-button,
input[type="number"]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}

Start by reproducing the reported JSS and Material UI example from the issue body, then compare its vendor-prefixed selector handling with the equivalent vanilla CSS behavior. Done means determining whether the selector is supported as written and documenting or correcting the usage, with a regression test if the repository provides a relevant selector test entry point.
