TS Errors on different lines - return with ternary

[lukpsaxo]

I've seen a few instances where errors are on different lines, which with suppressions causes tsgo errors on code that compiles with tsc.

Maybe this is an accepted breaking change?

One example is this:

type Y = {
  a: number;
  b: number;
};

function fetchA() {
  return { a: 1, b: 2 };
}

function getA() {
  return { a: 1, c: "123" };
}

async function X(d?: string): Promise<Y> {
  const z = getA();

  return d && d !== z.c
    ? fetchA()
    : // @ts-expect-error
      z;
}

in tsc the error is on z - in tsgo the error is on the return line.

In other cases I've seen errors on every property in a object where in tsc it errors on the top of the whole object so its not always "up" a node.
