Thanks for the workaround. Here are two things that I ran into when trying to use it:

1. It will not work with the browser-policy package because of executeScript.

I was getting this error specifically Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'unsafe-inline'".

2. The regex needs a bit of tweaking for LinkedIn because close will match the initial oauth popup.
