/**
* Emotion and Styled Components both allow users to pass through arbitrary props to their components
* to dynamically generate CSS. They both use the `@emotion/is-prop-valid` package to determine which
* of these should be passed to the underlying DOM node.
*
* However, when styling a Motion component `styled(motion.div)`, both packages pass through *all* props
* as it's seen as an arbitrary component rather than a DOM node. Motion only allows arbitrary props
* passed through the `custom` prop so it doesn't *need* the payload or computational overhead of
* `@emotion/is-prop-valid`, however to fix this problem we need to use it.
*
* By making it an optionalDependency we can offer this functionality only in the situations where it's
* actually required.

* String concatenation prevents bundlers like webpack (e.g. Storybook)
