Valid SCSS fails to build

**Problem**

The assets pipeline does not build when using CSS functions that clash with SCSS ones, such as [round](https://developer.mozilla.org/en-US/docs/Web/CSS/round).

I get the following error:

```
16:45:13 [dev] Build failed: Other(Failed to write assets

Caused by:
Error: Only 1 argument allowed, but 2 were passed.
╷
4 │ width: round(up, 10px);
│ ^^^^^^^^^^^^^^^
╵
```

I suspect it happens because it clashes with the `round` function from [sass:math](https://sass-lang.com/documentation/modules/math/#round), but I would have expected native CSS functions to take precedence, especially since `sass:math` is not even imported by this file.

**Steps To Reproduce**

Steps to reproduce the behavior:

- create a new Dioxus web project
- add the following SCSS file
```scss
# assets/hello.scss
.hello {
width: round(up, 10px);
}
```
- import it
```rust
const HELLO: Asset = asset!("/assets/hello.scss");
```
- run `dx serve`

**Expected behavior**

The application builds correctly.

**Environment:**

- Dioxus version: 0.6.3
- Rust version: 1.86.0
- OS info: Ubuntu 22.04.5 LTS
- App platform: web

**Questionnaire**

I'm interested in fixing this myself but don't know where to start.
