Incorrect type parameter in dts when imported as alias

[kevinresol]

import js.lib.Promise as AliasPromise;

typedef TypedefPromise<T> = js.lib.Promise<T>;

class Main {
	static function main() {}
	public static function f1<A>(p: js.lib.Promise<A>): Void {} // good
	public static function f2<A>(p: AliasPromise<A>): Void {} // bad
	public static function f3<A>(p: TypedefPromise<A>): Void {} // bad
}

generated:

export type TypedefPromise<T> = Promise<T>

export declare class Main {
	protected static main(): void
	static f1<A>(p: Promise<A>): void
	static f2<A>(p: Promise<T>): void
	static f3<A>(p: Promise<T>): void
}

and tsc will complain unknown type T and f2 and f3
