React 19.2

[Eliav2]

Note

Simplifies OverflowList visibility handling by removing React.Activity and pins workspace React packages to ~19.2.0.

• Components:
  • src/components/OverflowList.tsx:
    • Simplifies default renderItemVisibility: removes React.Activity usage and returns null for non-visible items, Fragment for visible ones.
• Config:
  • pnpm-workspace.yaml: Pins catalog entries for react, react-dom, @types/react, @types/react-dom from caret to tilde (~19.2.0).

Bug: React Activity Removal Undermines React 19+ Benefits

The removal of React.Activity component usage breaks the intended React 19.2+ feature. The code previously wrapped hidden items with Activity to keep them mounted while toggling visibility, but now always unmounts them by returning null. This contradicts the documented behavior and defeats the benefit of upgrading to React 19.2+, where hidden items should remain mounted via Activity to avoid state loss and flickering when children change sizes.

src/components/OverflowList.tsx#L229-L235

react-responsive-overflow-list/src/components/OverflowList.tsx

Lines 229 to 235 in 48204c9

	const finalRenderItemVisibility =
	renderItemVisibility ??
	((node, meta) => {
	if (!meta.visible) return null;
	return <React.Fragment key={meta.index}>{node}</React.Fragment>;
	});
