Patch Changes

• #1236 7ae32b5 - Stop the default scroll-adjustment heuristic from drifting the viewport when a viewport-spanning item grows. Previously any item whose top sat above the fold (itemStart < scrollOffset) had its size delta compensated on every re-measure — including a streaming chat message that spans the fold and grows at its bottom, dragging scrollTop downward token by token (#1218). Re-measurements now only compensate items that are entirely above the fold (itemStart + itemSize <= scrollOffset); growth below the anchor point leaves the scroll position untouched. First measurements (estimate→actual) still compensate any above-fold item, and a custom shouldAdjustScrollPositionOnItemSizeChange still overrides the default.
