*
* Format component stack into pseudo HTML
* component stack is an array of strings, e.g.: ['p', 'p', 'Page', ...]
*
* For html tags mismatch, it will render it for the code block
*
* ```
* <pre>
* <code>{`
* <Page>
* <p red>
* <p red>
* `}</code>
* </pre>
* ```
*
* For text mismatch, it will render it for the code block
*
* ```
* <pre>
* <code>{`
* <Page>
* <p>
* "Server Text" (green)
* "Client Text" (red)
* </p>
* </Page>
* `}</code>
* ```
*
* For bad text under a tag it will render it for the code block,
* e.g. "Mismatched Text" under <p>
*
* ```
* <pre>
* <code>{`
* <Page>
* <div>
* <p>
* "Mismatched Text" (red)
* </p>
* </div>
* </Page>
* `}</code>
