The react-beautiful-dnd → Pragmatic Drag and Drop migration in list_table landed without unit coverage for the new hooks (`use_list_table_dnd`, `use_list_table_row_dnd`), the new `row_drop_indicator` component, or the keyboard-reorder path in `list_table` itself. Add Jest coverage for all four, plus a regression block in `user_properties_table.test.tsx` that confirms the arrow-key reorder path on an existing list_table consumer still calls back into `reorderField` after the migration. - use_list_table_dnd: monitor registration lifecycle, canMonitor kind filtering, full getDropIndex truth table (top/bottom × source position), no-op when dropIndex == sourceIndex, useLatest pickup of onReorder without re-registration, dragKind change tears down and re-registers - use_list_table_row_dnd: initial null edge, no registration when rowElement is null or enabled is false, draggable + dropTarget registration, canDrop kind + rowId filter, getData edge payload, onDrag/onDragLeave/onDrop edge state transitions, cleanup on unmount, custom preview wiring - row_drop_indicator: render structure, edge prop forwarding, edge-change rerender (wrapped in act to settle floating-ui's flushSync autoUpdate) - list_table: drag-handle render variants (no onReorder, enabled, isRowDragDisabled), keyboard ArrowUp/ArrowDown dispatch with bounds, non-arrow no-op, drag-handle click does not bubble into row onRowClick - user_properties_table: regression coverage that the keyboard reorder path still resolves the correct UserPropertyField and next index for `reorderField` Co-authored-by: Cursor <cursoragent@cursor.com> |
