Can't make Parcel + Babel 7 + Jest work together

Question

I have a problem with making Parcel, Jest and Babel work with the same .babelrc

Parcel version: 1.11.0

Jest version: 24.0.0

Node: v10.5.0

Platform: Win 10

.babelrc

{
    "env": {
        "development": {
            "plugins": [
                [
                    "@babel/plugin-transform-runtime",
                    {
                        "corejs": 2
                    }
                ]
            ]
        },
        "test": {
        }
    },
}

If I move the plugins section to the root of the JSON it works correctly with the web app, however Parcel or Babel for some reason can't recognize the development env even if I set it in the command line.

If run the tests without the environment setup (having the env as above) then I get

 ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import _Promise from "@babel/runtime-corejs2/core-js/promise";

with Jest.

Probably the test setup wouldn't get recognized either, it just works without the babel/plugin-transform-runtime

Using this .babelrc solved it:

{
    "env": {
        "production": {
            "plugins": [
                [
                    "@babel/plugin-transform-runtime",
                    {
                        "corejs": 2
                    }
                ]
            ]
        },
        "development": {
            "plugins": [
                [
                    "@babel/plugin-transform-runtime",
                    {
                        "corejs": 2
                    }
                ]
            ]
        },
        "test": {
            "plugins": [
            ]
        }
    },
}
