import 'electron';
import HandlerDetails = Electron.HandlerDetails;

What is expected?

there's no generated import for alias import (HandlerDetails)

What is actually happening?

var import_electron = __toESM(require_electron(), 1);
var HandlerDetails = Electron.HandlerDetails;

Any additional comments?

We cannot write import type HandlerDetails = Electron.HandlerDetails because we run into error TS1392: An import alias cannot use 'import type'.

We can write import type { HandlerDetails } from "electron" in this particular case but it requires code changes for something that's unambiguously a namespace alias.
