defaultViewport not working in 2.0-beta

[jowan]

Describe the bug
defaultViewport as set in component story not respected.

To Reproduce
Steps to reproduce the behavior:

1. Create a list of custom viewports in preview.jsx
2. Create a component with its own stories.wingsuit.jsx
3. Add a default viewport to parameters as described in the add-on's docs (and wingsuit 1x)

Expected behavior
When viewing the component - the default viewport is applied

Additional context
I spun up a clean version of the Tailwind starter kit 2.0-beta.
It has some custom viewports already defined in its preview.jsx.
I can not make Storybook apply the default viewport.
This worked fine in wingsuit 1x but it's not working now :(

This does raise the question - do parameters work at all ? maybe it is not just viewport, maybe its the parameters object.

For reference, this is what I am doing, and it does not work.

import './index';

const patternDefinition = require('./fieldset.wingsuit.yml');

export const wingsuit = {
  patternDefinition,
  parameters: {
    viewport: {
      defaultViewport: 'sm',
    },
  },
};
