SCSS Styles doesn't preload.

[proskurindima]

Describe the bug and expected behavior

When I use SCSS, styles doesn't preload.
You can see it in codeSanbox

The same problem appears in my local environment.

Steps to reproduce

Steps to reproduce the behavior:

1. Add node-sass, sass and sass-loader packages in your package.json
2. Add some styles in <style> tag with attr lang="scss". For example:

<style lang="scss">
.test {
  font-size: 24px;
  font-family: sans-serif;
}
</style>

3. Reload page
4. See, that styles doesn't preload

Additional context

I've reproduced this error in codeSanbox.
