Profiling a 14-column virtualized table while scrolling: ~22% of the time went to Svelte's dev stack capture under
registerCellToken/unregisterCellToken, i.e. writes to the row'sSvelteSet/SvelteMap— every unregister rewrote the index of every later cell. The order is now a plain array (indexOfover a handful of cells), and the existingcellOrderEpochannounces a removal that shifts later cells. Regression test: removing a middle column moves the later cells'data-column-indexdown, header and body.🤖 Generated with Claude Code
