Cannot spread IButtonProps with react 16.8.5

Environment

• Package version(s): blueprint/core@2.1.1, React 16.8.5 (just upgraded from 16.3), typescript 3.3

Steps to reproduce

render() {
  const {buttonProps} = this.props; // type is IButtonProps
  <Button // compile error
    {...buttonProps} 
  />
}

Actual behavior

It looks like React.ButtonHTMLAttributes<T> has narrowed the button type from string | undefined to 'button' | 'submit' | 'reset' | undefined

Type '{} | { active?: boolean | undefined; alignText?: Alignment | undefined; elementRef?: ((ref: HTMLElement | null) => any) | undefined; fill?: boolean | undefined; large?: boolean | undefined; ... 10 more ...; className?: string | undefined; }' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<Button> & Readonly<IButtonProps & ButtonHTMLAttributes<HTMLButtonElement>> & Readonly<{ children?: ReactNode; }>'.
  Type '{ active?: boolean | undefined; alignText?: Alignment | undefined; elementRef?: ((ref: HTMLElement | null) => any) | undefined; fill?: boolean | undefined; large?: boolean | undefined; ... 10 more ...; className?: string | undefined; }' is not assignable to type 'Readonly<IButtonProps & ButtonHTMLAttributes<HTMLButtonElement>>'.
    Types of property 'type' are incompatible.
      Type 'string | undefined' is not assignable to type '"button" | "submit" | "reset" | undefined'.
        Type 'string' is not assignable to type '"button" | "submit" | "reset" | undefined'.

Expected behavior

No typescript compilation error

Possible solution

Use the same type as React for the type attribute in IButtonProps?
