Problem

Hello. We're trying to use sheets feature in our project. It looks good in ordinary usage but in our project we're using electron windows to render screens as separate windows. This project is actively uses global window and document elements. Can the code be adjusted to provide some windowService api so window object (and window.document as part of it) will be injected as dependency?
