[Bug]: should Play execute with `!test`?

[unional]

Describe the bug

export const ShouldNotPlay = {
  tags: ['!test'],
  // ...,
  play() {
    throw new Error('should not run')
  }
}

Should the play function be skip entirely when the story should be skipped in test?

The !test tag is respected by Storybook's test runners (like @storybook/addon-vitest or @storybook/test-runner), which means stories with this tag—and their play functions—are skipped during automated test runs. However, the play function will still run in the Storybook preview UI, since the preview does not skip stories based on the !test tag by default. If you want to prevent the play function from running in the preview as well, you'll need to add custom logic to conditionally skip it based on the tag.

You can read more about how the play function works in the official docs.
