Used Package Manager

bun

Expected Behavior

For the vanilla css styles corresponding link tag to be generated into the html in prod mode

Actual Behavior

This is not the case. Vanilla extract generates the css files, but does not inject the link tags in the html files. This has been tested on other vite projects and remix is the only one to fail

As mentioned in vanilla-extract-css/vanilla-extract#1479, the issue seems to be that remix is stripping side-effect imports for some reason. Regular imports of Vanilla Extract styles are unaffected.

Yes, and i should add that the package manager should not be relevant for this issue.
