missing dependency in @vitest/browser?

[phuhgh]

Describe the bug

I'm seeing an error being reported when running tests in the browser, this appears to be caused by a missing dependency:

3:38:02 PM [vite] Internal server error: Failed to resolve import "@vitest/runner" from "../../node_modules/.pnpm/@vitest+browser@4.0.15_vite@7.2.7_@types+node@24.10.1_terser@5.44.1_yaml@2.8.2__vitest@4.0.15/node_modules/@vitest/browser/dist/expect-element.js?v=779a201b". Does the file exist?

Looking at the package.json for @vitest/browser I note that "@vitest/runner": "4.0.15", is listed under devDependencies, but this is being used in @vitest/browser/dist/expect-element.js? Worth stating that the tests do actually run in spite of this...

Reproduction

Running tests in with either the provider @vitest/browser or @vitest/browser-preview seems to produce this issue. I tried creating a little demo project but that seemed to work, so I guess bringing in some particular matcher causes the issue.
