The syntax of `{{% code %}}` only expects Markdown inside. That's why it
triggers unsafe warning, if used as a shortcode template.
Instead the only the top table shortcode should be used as
`{{< tabs >}}` to include the HTML, while the user may use only
`{{% tab "Name" %}}` inside and be happily restricted to Markdown.
