Looks like Electron is implementing Picture in picture in the BrowserView. Its currently in a pull request. https://github.com/electron/electron/pull/17686
This is a feature also available as an extension from the Chrome Web Store. It's even developed by Google, but the issue with using Chrome extensions is of course probably some API it uses is missing, and it won't work on "protected" pages like the CWS.
