bug: Type 'void' is not assignable to type 'void' although not returning the expression

[trusktr]

input:

let s: string | null = null

declare function log(s: string): void

/** Calculates the n-th Fibonacci number. */
export function fib(n: i32): i32 {
  s != null ? log("not null") : log("null") // <--------------- error
  return 123
}

error:
