issue when using window.getComputedStyle in componentDidMount

[chrisdrackett]

I have a component similar to the following that renders fine in our app, however in the style guide it raises errors on window.getComputedStyle(this.element).fontSize. I'm not sure exactly what the bug is, but figured it was worth raising.

import React, { Component } from 'react'

export default class Sample extends Component {

  componentDidMount = () => {
    const x = window.getComputedStyle(this.element).fontSize
    console.log(x)
  }

  render() {
    return (
      <div ref={(element) => this.element = element}>
        Test.
      </div>
    )
  }
}

Hey @chrisdrackett, I'm facing a similar issue with jquery. I'm using it from the window as window.$ and it says undefined. Could you point me to how you figured this out?
