@cleer, what should the behavior be if the user changes scroll direction when the infobar is partially hidden? As of now, the infobar will retain its current visibility and not change until the toolbar is completely shown or hidden.

One possible alternative is to snap the infobar to full or hidden if the direction changes.

[Home] Only animate infobars after toolbar has finished

To reduce the amount of visual noise at the bottom of the screen when
Chrome Home is enabled, infobars will only scroll after the toolbar
has stopped moving.

- When appearing, the infobar will begin showing only after the
  toolbar is completely visible.
- When hiding, the infobar will not hide until the toolbar is
  completely invisible.
- If the scroll direction changes while the infobar container is not
  completely shown or hidden, it will snap to the nearest state.
