Reproduce the issue in the linked StackBlitz example with a custom .vue component under /components/global and nuxt-modules/icon. Compare the behavior with issue #590 and trace how Histoire discovers global components. Done means the custom icon component renders when used from the story at components/TestIcon.story.vue.
