Hello! I wanted to make simple source transform, as intended by your library. I do everything like documentation says here: https://rollupjs.org/plugin-development/#source-code-transformations using this example, rollup produces sourcemap as it was in the original file (file transform does work though) some guy on the internet have exactly the same problem (at least had it last year, I guess it's not solved) here: https://stackoverflow.com/questions/77607028/rollup-transform-of-file-including-sourcemap-for-vite I'll also try and reach people from rollup, but maybe I can get my solution here thanks!
