Allow the use of ">" in CSS selectors for the Style tag

**Is your feature request related to a problem? Please describe.**
There are times when I would like to style an HTML element that can only be selected through the use of `>` to identify a descendant in a CSS selector. However, the Style tag does not support this, as it encodes the `>` into `>`.

For example:
```

span > label{
background-color: pink
}

```
becomes
```

span > label{
background-color: pink
}

```
which doesn't do anything.

**Describe the solution you'd like**
I would like `>` to remain a `>` when used inside Style tags.

**Describe alternatives you've considered**
* What I would _really_ like is the ability to use external stylesheets, as in ``. But this seems like a smaller ask.
* I guess I could accomplish arbitrary feats of CSS through the use of a browser extension.
