I opened Google Keep in Google Chrome, then I focused another window while it was loading.  Suddenly, Chrome re-focused itself!  While I was typing in another window!  (I even minimized the window, and it un-minimized it)How does it do this and how can I turn it off?  I didn't think browsers let you do that with JavaScript.  Is it an extension or something built-in to Chrome?I made a quick screencast.  Here's a video of what is happening: http://youtu.be/6zcVbqpHciM
