No service worker shown in Chrome extensions after adding chromiumArgs user-data-dir

Describe the bug

Hi,

npx wxt@latest init
choose Vue
npm run dev
see Chrome > Manage extensions. It shows link to inspect service worker (good)

Edit wxt.config.ts to add chromiumArgs:

import { defineConfig } from 'wxt'

export default defineConfig({
    modules: ['@wxt-dev/module-vue'],
    webExt: {
        chromiumArgs: ['--user-data-dir=./.wxt/chrome-data'], // remember browser state between runs
    },

})

npm run dev
Chrome > Manage extensions. link to inspect service worker is not shown

Validations

• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

Start with the minimal reproduction in wxt.config.ts: add the chromiumArgs user-data-dir setting and run npm run dev, then compare Chrome's Manage extensions page with and without it. Trace the development browser launch and extension-loading entry points to identify why the service-worker inspection link disappears; done means the link remains available while browser state persists.
