I have a project that uses vitest with happy-dom in conjunction with vite-plugin-solid. Switching from 2.7.0 of vite-plugin-solid to 2.7.1 breaks my unit tests.

Here's a relevant part of the test section of vite.config.mts:

  test: {
    environment: 'happy-dom',
    globals: true,
    server: {
      deps: {
        // fixes: You appear to have multiple instances of Solid. This can lead to unexpected behavior.
        inline: [/solid-js/, /solid-testing-library/],
      },
    },
    deps: {
      // fixes: Vitest "deps.registerNodeLoader" is deprecated. If you rely on aliases inside external packages, use "deps.optimizer.web.include" instead.
      optimizer: {
        web: {
          enabled: true,
        },
      },
    },

When I run vitest with vite-plugin-solid 2.7.0, everything works fine. When I run it with 2.7.1, I get:

 Vitest  "deps.registerNodeLoader" is deprecated.If you rely on aliases inside external packages, use "deps.optimizer.web.include" instead.
 MISSING DEP  Can not find dependency 'jsdom'

? Do you want to install jsdom? › (y/N)

The fact that it's not honoring either the environment: 'happy-dom' setting or the setting that suppresses the registerNodeLoader warning makes me think that something about 2.7.1 is preventing the test config from being loaded at all.
