forms-reducer contains trailing comma after rest property, preventing transpiling for Jest

The Problem

Running Jest tests with my project requires transpiling react-redux-form. In doing so with Babel 7.2.2 with @babel/plugin-proposal-object-rest-spread 7.3.1, an error is thrown:

SyntaxError: /Users/....../frontend/node_modules/react-redux-form/src/reducers/forms-reducer.js: > A trailing comma is not permitted after the rest property (39:20)

According to the spec, trailing commas are not allowed after the rest property.

Steps to Reproduce

Transpile with Babel 7.2.2 and @babel/plugin-proposal-object-rest-spread 7.3.1

Here is my relevant Jest config:

jest.config.js

module.exports = {

  // Automatically clear mock calls and instances between every test
  clearMocks: true,

  // A map from regular expressions to module names that allow to stub out resources with a single module
  moduleNameMapper: {
    '\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$': '<rootDir>/__mocks__/fileMock.js',
    '\\.(css|less)$': '<rootDir>/__mocks__/styleMock.js',
  },

  // An array of regexp pattern strings that are matched against all source file paths, matched files will skip transformation
  transformIgnorePatterns: [
    '/node_modules/(?!(react-redux-form)/)',
]
};
