Style loader data remains in iframe when changing stories

[ozzyogkush]

Describe the bug
When switching between viewing stories, the <style> tags from previous style-loader outputs remain in the preview iframe.

To Reproduce
Steps to reproduce the behavior:

1. Make a story that addDecorator() that requires() a SASS/CSS file
2. Make a separate story that does not
3. View the first story
4. View the second story
5. The second story has the first story's CSS applied to it

Expected behavior
Each story preview iframe only shows loaded styles for decorators and components directly used in that story.

Code snippets

// appSassDecorator
export default story => {
    require('js-file-that-includes-sass');

    return story();
};

// story 1
const stories = storiesOf('First Set', module);
stories
  .addDecorator(appSassDecorator)
  .add('Story 1', () => <div>Should Include Styles</div>);

// story 2
const stories = storiesOf('Different Set', module);
stories
  .add('Story 2', () => <div>Should NOT Include Styles</div>);

System:

• OS: OSX
• Device: MBP 2018
• Browser: Chrome
• Framework: React
