Vue.js: 'Error' props throw error

[artemi5c]

Hello there!

Describe the bug With vue.js, when a component is passed a string that contains 'error' as a prop, Storybook throws an error.

I upgraded to 5.2.8. Everything worked fine in 5.1.8

To Reproduce

• Create a story with a Vue component
• Pass a string containing 'error' as a prop

Expected behavior Story displays correctly

Screenshots A good component:

A broken component
