Input Code

https://github.com/dgeibi/babel7-ie10-class-inheritance-bug/blob/master/src/index.js

Expected behavior/code

Static methods inheritance works in IE10.

Babel Configuration (.babelrc, package.json, cli command)

{
  "presets": [
    ["@babel/preset-env", {
      "modules": false,
      "useBuiltins": "usage"
    }]
  ],
  "plugins": [
    "@babel/plugin-transform-runtime"
  ]
}

Environment

• Babel version(s): v7.0.0-beta.48
• Node/npm version: Node10/npm6
• OS: Windows 10
• Monorepo no
• How you are using Babel: loader

If .babelrc is

{
  "presets": [
    ["@babel/preset-env", {
      "modules": false,
      "useBuiltins": "usage"
    }]
  ],
  "plugins": [
    "@babel/plugin-transform-proto-to-assign"
  ]
}

In IE10, result will be
