Conditional type *without union* behaves differently when inlined #36135

type MyExtract<T, U> = T extends U ? T : never

function foo<T>(a: T) {
  const b: Extract<any[], T> = 0 as any;
  a = b; // ok

  const c: (any[] extends T ? any[] : never) = 0 as any;
  a = c; // FAILS
//^ Type 'any[] extends T ? any[] : never' is not assignable to type 'T'.
//    'any[] extends T ? any[] : never' is assignable to the constraint of type 'T', but 'T' could be instantiated with a different subtype of constraint '{}'.
//      Type 'any[]' is not assignable to type 'T'.
//        'any[]' is assignable to the constraint of type 'T', but 'T' could be instantiated with a different subtype of constraint '{}'.(2322)

  const d: MyExtract<any[], T> = 0 as any;
  a = d; // ok

  type CustomType = any[] extends T ? any[] : never;
  const e: CustomType = 0 as any;
  a = e; // FAILS
//^ Type 'CustomType' is not assignable to type 'T'.
//    'CustomType' is assignable to the constraint of type 'T', but 'T' could be instantiated with a different subtype of constraint '{}'.
//      Type 'any[]' is not assignable to type 'T'.
//        'any[]' is assignable to the constraint of type 'T', but 'T' could be instantiated with a different subtype of constraint '{}'.(2322)
