worker.rollupOptions do not seem to work in lib mode

[ivancuric]

Describe the bug

It seems that no options in worker.rollupOptions seem to work.

I have tried to rename the worker asset output name without any success. Repro sample is linked and can be tested by running npm run build.

And a follow up question: is it possible to disable Vite from creating the worker output as an asset in the first place and just compile the worker file by itself?

This is a duplicate of #7928 and fixed by #7804. Please upgrade to 3.0.0.

I'm not sure how you are going to compile the worker, but I think it is possible by creating a plugin with enforce: 'pre'.
