Not seeing on minnie running canary (8743.0.0), what device did you see this on?

Pixel 2. You need to reboot fully. Upon logout it looks fine oddly enough.

Screenshot?

Okay finally was able to track this one down. Two screenshots from Minnie, note the size difference. It is even more pronounced on Samus.

+yoshiki@ who has worked on notifications recently

yoshiki@ are you the right person to tackle this one?

This is because the tray on login screen doesn't have an avatar icon. Let me fix this.

The following revision refers to this bug:

The height of the status tray should be 37px, but it wasn't on login and lock screen. This patch fixes it.

Major changes:
1) Sets the minimum height 37px (kTrayItemSize actually)
2) Removes the vertical margin of web notification tray. this is no longer necessary thanks to #1.
3) Removes the hack for win in ShelfLayoutManagerTest::StatusAreaHitBoxCoversEdge.

Set status bar height to 44px on login screen

The height of the status bar is 44px on normal screen, but is 48px on login and lock screen. This patch makes the login screen 44px, by reducing 3px black bottom border and 1px top margin. As the result, the height of top and bottom margin and tray are same among login, lock and normal screen.
