Fix status bubble visibility — use top offset instead of bottom-full

bottom-full anchored the bubble above the avatar block's top edge, which
margin-collapses up into the banner, pushing the bubble off the visible
area. Position it with a top offset within the same coordinate space the
original used, lowered so its tail rests at the banner's bottom edge.
