Found on r606182. 

What steps will reproduce the problem?
(1) Open a browser window and navigate away from new tab page
    e.g. go to "google.com";
(2) Swipe down on the tab in tab strip;

What is the expected result?
The tab is minimized.


What happens instead?
The tab is minimized then restored. See attached video.

The problem seems to be at TabDragController::RestoreFocus [1] called from TabDragController::EndDragImpl. When we are not in newtab page, FocusLocationBarByDefault returns false and we would focus on the content area which would activate the browser window.
