Sorry, I'm missing a lot of context, but it seems like `@function` is working the way I described ([example](https://codepen.io/Steve-Orvell/pen/MYKXwjg?editors=1000))? Is the processing model different for ` @mixin/@apply`?

```html
<style> @function --m() { result: 'first'; } </style>

<div><template shadowrootmode=open>
  <style> #inner::after { content: 'shadow:' --m(); } </style>
  <div id=inner></div>
</template></div>

<style> #inner::after { content: 'document:' --m(); } </style>
<div id=inner></div>

<style> @function --m() { result: 'second'; } </style>
```
