Issue with switching between containers during OAuth sign-in.

[dadinn]

Before submitting a bug report

• [X] I updated to the latest version of Multi-Account Container and tested if I can reproduce the issue
• [X] I searched for existing reports to see if it hasn't already been reported

Step to reproduce

Create a Google container for https://mail.google.com and https://accounts.google.com, and another Youtube container for just https://youtube.com, and set the Always open in this site in container option for each.

Actual behavior

Youtube is opened in its own container. When one tries to login, they get redirected to https://accounts.google.com in the Google container. There one completes the login to the account, and then get redirected back to Youtube, which in turn switches back to the Youtube container. Because of the login happens scattered between the containers, the Youtube won't find the session cookie, and gets redirected to the login page in the other container, and the endless cycle starts again...

Expected behavior

When using a private window, this issue is not there. It should be possible to address this in similar manner, somehow ensuring the switching to the OAuth login page happens in the same container where it started from. Maybe by introducing some way to temporarily override the global settings.

Additional informations

Updated add-on/extension to latest version 8.1.3.

Would be nice to be able to tell the extension that next click is going to be oauth and please don't switch to remembered container for the site.
