Opening the preview panel narrows .grid-area and reflows the auto-fill grid
to fewer columns, moving the clicked card to a new row. The single-frame
scrollIntoView ran while the browser's scroll-anchoring re-adjusted scrollTop
mid-reflow, so the card scrolled out of view. Disable scroll anchoring on
.grid-area (overflow-anchor:none) and defer the scroll by two animation
frames against the settled layout, centring the card (block:'center').
