I believe this is an issue with redirecting domains. For example, if you have set foo.com to automatically open in a specific container, and you enter www.foo.com into your default tabs, it will try to load www.foo.com in the default tab, then get redirected to foo.com, then realize it needs to be open in a specific container, then open a new tab in that specific container with foo.com. A good workaround for this could be to let users add arbitrary domains to their container whitelists (so you could manually add www.foo.com), but I haven't found a way to do that yet.
