/**
* Wrapper component used to decorate all of our stories by providing access to
* `in-content/common.css` without leaking styles that conflict Storybook's CSS.
*
* More information on decorators can be found at:
*
* @property {Function} story
* Storybook uses this internally to render stories. We call `story` in our
* render function so that the story contents have the same shadow root as
* `with-common-styles` and styles from `in-content/common` get applied.
* @property {Object} context
* Another Storybook provided property containing additional data stories use
* to render. If we don't make this a reactive property Lit seems to optimize
* away any re-rendering of components inside `with-common-styles`.
