Using the inputs you can add values to the map.
The console.log shows you all the map content, but using vue-devtools it is not possible to inspect the map.
You can only see "myMap: Map" .. so you can see that it is a map, but cannot see what it contains.

What is expected?

that i can see the Maps content by inspecting the map using the vue-devtools

What is actually happening?

Its only displayed that the data is from type Map, but you cannot interact with it, you cannot inspect its content

Reproducable with vue version 2.5.17 in latest nuxt version

Anything new on this?

Could you post the reproduction again? The links in the OP are dead. Anyway I can't reproduce it on the dev app:

@Akryum thank you for your reply. I restored the example links.
I still only see myMap: Map in the vue-devtools but maybe i'm handling the map wrong?

[Akryum]

I guess it's happening because you are using a polyfilled Map which is then technically not the same as the native Map and causes myMap instanceof Map to return false.
