Invalid path handling with CSS, when unbundle is true on Windows #319
Description
Reproduction link or steps
Repro : https://github.com/stevebeauge/tsdown-css-windows-repro
pnpm build => OK
pnpm build --unbundle => KO
Same with setting unbundle through the config file
What is expected?
When using unbundle parameter, and CSS files, the emitted CSS files should be inside dist folder.
src/MyComponent.module.cssshould outputdist\MyComponent.module-BlAtsAg0.css(or whatever hash)
What is actually happening?
Using Windows, the output path is src\MyComponent.module-BlAtsAg0.css (inside the src folder).
Full console output:
tsdown "--unbundle"

Seems there's something missing in path normalisation
Any additional comments?
