weird interaction with storybook 5 breaks compilation

[cellog]

As referenced here: storybookjs/storybook#5882

Greenkeeper asked us to upgrade from 4.1 to 5.0 of storybook, and now, suddenly, we get failures where the styled components babel plugin is replacing imports with declarations:

ERROR in ./src/components/creator/lock/KeyList.js 13:15
Module parse failed: Unexpected keyword 'var' (13:15)
You may need an appropriate loader to handle this file type.

The PR that shows these errors is unlock-protocol/unlock#1877

I have not yet tried to isolate this, would love some ideas of why this might be happening so I know what to isolate.

Closing as it appears to be a storybook issue reading through the linked thread that is now closed.
