The backend-integration test that imports a CSS file and also linked it was failing if we only avoid the optimization for direct requests. So the PR now bails out of it for all CSS files. |

Description
Fixes ttps://github.com/danielroe/css-flash-repro
The check we added in #15586 to detect mixed etags between direct and imported CSS was wrong. See explanation here to understand the problem: https://github.com/vitejs/vite/pull/15586/files#r1453060051. The issue is that
isDirectRequestdoesn't work because the query isn't added until the transform middleware kicks in.This PR fixes the issue by reverting back to the previous 304 scheme for direct CSS requests. Imported CSS and all JS files will still go through the optimized path.
If we move from
?directto marking with?importas we do with assets, we may be able to optimize direct CSS imports too.What is the purpose of this pull request?
