Page reload not working for ?raw CSS imports

Describe the bug

The title says it really; page reload appears to have stopped working in Vite 5 for ?raw CSS (and possibly other) imports. I checked back and it is working in the latest v4 but looks to have stopped in v5. I've created a couple of projects on StackBlitz to show it working in v4 and not in v5 (remove commented out background-color on body and save).

We're using the imports to pull related CSS into (Lit) web components, which we've done purely to keep the JS/CSS separate and make things easier to work with. Any help will be much appreciated, as is all your hard work to date. Many thanks!
