I've spent quite a bit of time looking at how the Google Dictionary extension creates its floating popup, but I could not understand how it somehow magically manages to "hide" itself from the DOM / "Elements" tab in the DevTools. Also in the page context I can do a document.getElementById("gdx-bubble-host") while it's displayed, but innerHTML is blank!
WTF?

It uses Shadow DOM, dude. :)
And it appends its main element to <body>.
