Namespace 'React' has no exported member 'JSX'

If I check TypeScript types inside an ESM package that (indirectly) uses rc-tree, I get type errors from inside node_modules:

Reproduce the TypeScript errors in an ESM package that indirectly uses rc-tree, then inspect the reported declarations in lib/DropIndicator.d.ts, lib/Tree.d.ts, and lib/TreeNode.d.ts. The work is done when the affected type declarations no longer produce the reported React.JSX errors in that setup.
