error TS2420: Class 'Chromeless<T>' incorrectly implements interface 'Promise<T>'

[mqudsi]

Chromeless 1.5.0 under TypeScript 1.7.2 imported as

import { Chromeless } from "chromeless";
// or 
// import Chromeless from "chromeless";

returns the following error when the compiler attempts to resolve all dependencies:

node_modules/chromeless/dist/src/api.d.ts(2,22): error TS2420: Class 'Chromeless<T>' incorrectly implements interface 'Promise<T>'.
  Property 'finally' is missing in type 'Chromeless<T>'.

My compiler options (tsconfig.json) are as follows:

{
	"compilerOptions": {
		"target": "es5",
		"lib": ["dom", "esnext"],
		"module": "commonjs",
		"declaration": true,
		"moduleResolution": "node",
		"sourceMap": true
	}
}

Experiencing the same problem - my workaround is to remove esnext from libs, as Promise.finally is part of esnext.
