Setting server open to true focuses the tab when config.mts is changed

[gkiely]

Describe the bug

Setting server open to true in the config.mts and changing the config will focus the localhost tab, this is unexpected and differs from how vite behaves normally.

Reproduction

import { defineConfig } from 'vitepress';

// https://vitepress.dev/reference/site-config
export default defineConfig({
  title: "Example project",
  description: "An example project",
  themeConfig: {
    // https://vitepress.dev/reference/default-theme-config
    nav: [
      { text: 'Home', link: '/' },
      { text: 'Examples', link: '/markdown-examples' }
    ],

    sidebar: [
      {
        text: 'Examples',
        items: [
          { text: 'Markdown Examples', link: '/markdown-examples' },
          { text: 'Examples', link: '/examples' }
        ]
      }
    ],

    socialLinks: [
      { icon: 'github', link: 'https://github.com/vuejs/vitepress' }
    ]
  },
  vite: {
    server: {
      open: true,
    }
  },
})

Expected behavior

Tab does not focus

1.3.0

Looks like vite.open is not supported yet. If you run with vitepress dev docs --open it should work fine.

Released a fix in v1.3.1. Should work fine now.
