Vite ruby plugin causes server options to be ignored

[bogdan]

• [x] I have tried upgrading by running bundle update vite_ruby.
• [x] I have read the troubleshooting section before opening an issue.

Description 📖

RubyPlugin in vite config causes server options like host or port to be ignored.

Reproduction 🐞

Please provide a link to a repo that can reproduce the problem you ran into.

rails new vite-rails-test
cd vite-rails-test
bundle add vite_rails
bundle install
bundle exec vite install
 ./node_modules/vite/bin/vite.js --host=0.0.0.0

Expected:

  VITE v5.4.19  ready in 766 ms

  ➜  Local:   http://localhost:5173/
  ➜  Network: http://192.168.1.171:5173/
  ➜  press h + enter to show help

Actual:

  VITE v5.4.19  ready in 108 ms

  ➜  Local:   http://localhost:3036/vite-dev/
  ➜  press h + enter to show help

The bug goes away if RubyPlugin is commented out in vite.config.mts
