Error and Issue with window.open

In readme, there is a line which means, window.open is overwritten from inAppBrowser

window.open = cordova.InAppBrowser.open;

How can I fix this in my Ionic App?

My Problem: I use Facebook Login Plugin, and this Plugin opens window.open -> but here it crashes and I got an Error.

How to avoid overwriting window.open with the InAppBrowser? There is no working example in the internet.

Start with the README line that assigns window.open to cordova.InAppBrowser.open, then reproduce the Facebook Login Plugin crash in an Ionic app. Determine and document a working way to avoid that overwrite while preserving InAppBrowser behavior; the issue provides no named test or implementation file.
