[bug] CSS randomly applied using Sveltekit + Tauri (v1 and v2)

[CraneCristal]

Describe the bug

When launching tauri in dev mode, some CSS is not applied, and it changes from one launch to another. It seems like the scoped CSS is randomly applied or not.

• launch 1 (css randomly applied)
  

• launch 2 (no code change but everything seem correct this time)
  

I cannot reproduce the same issue in browser and the only workaround I find for now is to reload all with ViteJs.
The issue does not happen in build.

Can you test it in epiphany (also known as Gnome Web) too? It's a browser using webkitgtk like tauri. This way we can check whether it's an upstream issue or our fault.
