1) Go to a website that displays notifications (example: https://atwilson.users.x20web.corp.google.com/www/notif_test.html)
2) Have the website display the notification
3) Focus a different window
4) Click on the notification

Expected:
The chrome window that displayed the notification comes to the foreground. I thought at one point it would also switch to the tab, but maybe we rely on the page to call window.focus() for that?

Actual:
For native notifications (on Linux): chrome window is indeed focused
For non-native notifications (enabled via chrome://flags/#enable-native-notifications), clicking on the notification does not focus the chrome window.

Non-native notifications should have the same behavior as native notifications re: focusing the window.

I have not tested this on non-linux platforms.
