Delayed CSS loading with asset system

**Problem**

When using the asset system to add CSS, the styling is loaded later than when using `Doxus.toml` and results in the components being unstyled at first.

**Steps To Reproduce**

Steps to reproduce the behavior:

- Or `style = ["/tailwind.css"]`
- Use `head::Link { rel: "stylesheet", href: asset!("./assets/tailwind.css") }`

**Expected behavior**

Everything should be styled when it appears.
