Storybook 8.0.0-beta.3 bug reproduction

Issue: storybookjs/storybook#26111

This repository demonstrates an existing bug in Storybook version 8.0.0-beta.3 (also occurring in 8.0.0-beta.2).

Steps to preproduce:

• Clone the repository
• npm run install
• npm run storybook
• Go to story "label (non-working-component 1 or 2)"

---

Reproducing this is trivially simple, all you need to do is define Stories that pass JSX to the used component instead of just a string.

Example:

Working stories: ✅

export const LabelStory: Story = {
  name: "label (working component)",
  args: {
    label: 'Hi, this component fully works.',
  },
};

Non-working stories: ❌

export const LabelStory2: Story = {
  name: "label (non-working component)",
  args: {
    label: <span>Hi, this component causes storybook crash :(</span>,
  },
};

It also doesn't matter whether the prop provided in args is handled in the component.

Example:

export const LabelStory3: Story = {
    name: "label (non-working component)",
    args: {
        label: 'Hi, this component should fully works...',
        randomUnhandledPropInComponent: <span>...but trying to pass JSX prop causes it to crash:/</span>
    },
};
