I'm running some examples locally and 2nd import doesn't get hoisted?

  expect(await ssrTransformSimpleCode(`\
console.log(foo.bar);
console.log(foo2.bar);
import foo from 'libx';
import foo2 from 'liby';
`)).toMatchInlineSnapshot(`
  "const __vite_ssr_import_0__ = await __vite_ssr_import__("libx", {"importedNames":["default"]});
  console.log(__vite_ssr_import_0__.default.bar);
  console.log(__vite_ssr_import_1__.default.bar);
  const __vite_ssr_import_1__ = await __vite_ssr_import__("liby", {"importedNames":["default"]});
