proxyMap doesn't work with Redux DevTools

[NeilTheFisher]

A workaround is required to show Maps on the Redux DevTools, and when the value is changed in the DevTools, it doesn't update the original.

What I did in the reproduction below converts the map to an object so display it's data but this makes it impossible for the DevTools to update the original unless some trickery subscribe on the debugState is done, though it wouldn't be hard to implement.

Building this functionality into the devtools function if a Map or Set is used would be great.

It looks like it's possible to have the Redux DevTools serialize maps this way:

const store = Redux.createStore(reducer,
 window.__REDUX_DEVTOOLS_EXTENSION__ &&
 window.__REDUX_DEVTOOLS_EXTENSION__({
  serialize: { 
    options: {
     map: true,
    }
  }
}));

If the DevTools can do this, then it can likely also update the Map as well.
Though I'm skeptical about this working since a proxyMap is just an emulation of an actual Map.

Me too.
