Cannot import external es6 module correctly

I have a typescript project, the ts files are stored in different directories, they all import the same external module, like this:

/main.ts:

```
import * as ext from 'external';
import { g } from './lib/foo';
function f() {
g();
ext.func1();
}
```

/lib/foo.ts:

```
import * as ext from 'external';
function g() {
ext.func2();
}
```

I want to package main.ts into an ES6 module and store it in the same directory as external.js
After packaging, I expected to get this result:

main.js:

```
import * as ext from './external.js";
// blah blah
```

My packaging script looks like this:

```
microbundle -i main.ts --no-pkg-main -f modern --target web -o dist/main.js --external .*/external.js --alias external=./external.js

```

But I got this result:

```
import * as ext$1 from './external.js';
import * as ext from './lib/external.js';
```

I think this should be because the two ts files are in different directories and aliases are used, but what should be the correct way?

Reproduce the packaging command with main.ts, lib/foo.ts, and the external module, then inspect dist/main.js. Compare how each source import is resolved and verify that both references to external produce the intended shared ./external.js import. The issue is done when the generated ES6 module has the expected external import without the incorrect lib/external.js path.
