Higher Order Component redux dispatch being overwritten by wrapped component redux dispatch

It looks like you have an issue with your example.

function withExtraStuff (InnerComponent) {
  return class Enhancer extends React.Component {/* ... */}

  // ...

  return connect(/* ... */)(Enhancer)

You're returning twice from your HOC, so your Enhancer is never connected.

Is this just a typo in your example? Or do you have this same issue in your code? Because that would indeed cause the issue you're seeing.
