Description

With the following setup, there is an error in file-b:

file-a.js export opaque type Foo: string = string;

file-b.js export type { Foo } from './file-a';

However if the code in file-b.js is written differently (see below), it works fine.

file-b.js import type { Foo } from './file-a'; export type { Foo };

Hence I think this is a bug.

Contributor guide

Research direction
Investigate the import handling logic for re export of opaque Flow types; ensure that the parser correctly handles the `export type { ... } from` syntax.
