preserveSymlinks breaks useQuery return type

[dylan-chong]

Describe the bug

// package.json
{
  "dependencies": {
    "@tanstack/react-query": "5.48.0"
  },
  "devDependencies": {
    "typescript": "5.5.2"
  }

// tsconfig.json
{
    "compilerOptions": {
        "lib": ["dom", "esnext"],
        "preserveSymlinks": true
    }
}

// index.js
import { useQuery } from '@tanstack/react-query';
const { data } = useQuery({ queryFn: () => Promise.resolve(3), queryKey: ['alskdjf'] })
data; // hover this in IDE

with preserveSymlinks true, hovering in IDE shows "const data: QueryObserverResult<TData, TError>". bad type inference with preserveSymlinks false, hovering in IDE shows "const data: number" which is (almost) correct. it should be "number | undefined"

2 problems here, but the first one is the main one

works on my machine (same TS version, flag on):

could also be an issue with TS 5.5.2

• https://github.com/microsoft/TypeScript/issues/58937

but in any case, I don't think there's any action we can take.
