Typescript: rows/columns attribute missing from <gridlayout>

[timbasel]

The rows and column attributes (and maybe more) is missing from the type of the element.

export const App = () => {
  return (
    <gridlayout rows="*,50">
      ...
    </gridlayout>
  )
}

ERROR in ./app/app.tsx
TS2322: Type '{ children: Element[]; rows: string; }' is not assignable to type 'JSXElementAttributes<"GridLayout">'.
Property 'rows' does not exist on type 'JSXElementAttributes<"GridLayout">'. Did you mean 'row'?

Functionally everything works, only the typings are incomplete.
