    "exclude": [ "src/fonts", "src/icons", "src/less", "src/vector-icon" ],
    "includePattern": ".+\\.js(doc|x)?$",
    "excludePattern": "(^|\\/|\\\\)_"
  },
  "plugins": ["node_modules/jsdoc-babel"],
  "babel": {

  },
  "jsx": {
    "extensions": ["js", "jsx"]

Class properties aren't part of the ES2015 spec, so they're not part of the ES2015 Babel preset either. The proposal to add class properties to the language is currently at Stage 3 of the standardization process, so you need the Stage 3 preset.

Alternatively, you could just install the class properties plugin on its own:
