The problem is described in rolldown/rolldown#3640. Setting experimental.viteMode enables a similar behavior with commonjs plugin, but it was only set to the main build and not to the worker build. This PR sets that to the worker build as well. I think it'd be better to migrate to module.exports export, but I think it's ok for now.

fixes vitejs#610
