Phase 2 of the anchored turn (following the live edge once the reply
outgrows the viewport) never ran: the reveal correction was triggered
only by entries-array changes, and the streaming tail grows inside a
single row without touching the array. The hook now also subscribes to
LegendList's totalSize and re-runs the same guarded correction on every
content growth.
