beforeLoad return type circular reference error regression somewhere between versions 1.130.12 and 1.134.13

Which project does this relate to?

Router

Describe the bug

This piece of code

export const Route = createFileRoute('/_authenticated')({
  beforeLoad: ({ context }) => {
    return {
      crumbs: [
        ...context.crumbs,
        {
          text: 'Some Text',
          // ❌ This line breaks type inference
          to: Route.fullPath,
        },
      ],
    };
  },
  component: RouteComponent,
});

works ok in 1.130.12 without any TS errors

Steps to Reproduce the Bug or Issue

Use the code example above in versions beyond 1.130.12. The fact that we are using the Route reference inside beforeLoad causes the type error. (there is no actual runtime error, since this is valid object reference inside the function body, similar to

function createObj(x: string) {
  return function <T>(x: T) {
    return x
  }
}

const test = createObj('')({
  a: 1,
  func: () => {
    return test.a
  },
})

)

Expected behavior

For the above code to work with no type errors
