Typings Issue: Interface 'ImageProps' cannot simultaneously extend types ...

[Robert-Fairley]

Problem description

Simple app won't build due to typings issue.

The error at the end of the Webpack build process is:

ERROR in [at-loader] ./node_modules/react-uwp/Image/index.d.ts:18:18
    TS2320: Interface 'ImageProps' cannot simultaneously extend types 'DataProps' and 'HTMLAttributes<HTMLDivElement>'.
  Named property 'placeholder' of types 'DataProps' and 'HTMLAttributes<HTMLDivElement>' are not identical.
