bundle regression since 1.8.0: module import loss after 3 levels of re-export

[nktpro]

Here's another bizarre deno bundle regression since 1.8.0. Given

first.ts

export const foo = "foo";

second.ts

export * from "./first.ts";

third.ts

export * from "./second.ts";

fourth.ts

import { foo } from "./third.ts";
console.log(foo);

deno bundle ./fourth.ts will produce an invalid output of:

console.log(foo);

Note that foo is gone and is never declared in the output. However, if there are only 2 levels of export, where:

third.ts

import { foo } from "./second.ts";
console.log(foo);

Then deno bundle ./third.ts will produce the correct output of:

const foo = "foo";
console.log(foo);

I could only re-produce this from 1.8.0 onwards, so it seems to be a fairly new regression in swc.
