Re-exports of multiple "declare global" statements generate incorrect declaration file

[Septh]

@wessberg/rollup-plugin-ts: 1.2.25
rollup: 2.15.0
typescript: 3.9.5

Try the following:

// src/lib/a.ts
declare global {
    const good: string
}
export const a = good

// src/lib/b.ts
declare global {
    const bad: string
}
export const b = bad

// src/index.ts
export { a } from './lib/a'
export { b } from './lib/b'

Then, the generated code is fine:

// out/index.js
const a = good;
const b = bad;
export { a, b };

But the corresponding declaration file is not:

// out/index.d.ts
declare global {
    const good: string;
}
declare const a: string;
declare global$0 {
    const bad: string;
}
declare const b: string;
export { a, b };

The second declare global should not be renamed and ideally the two statements should be merged as one.

Hey there. Thanks for the repro instructions. The problem has been fixed and will be released as part of v0.0.27.
