If there's an error when formatting with external formatter, error message will be like:
Message: [markup_fmt] failed to format code with external formatter: `<>{content += '{"hello": "I\'m a button!"}'}</>`:
Expected ',', got '+=' at file:///expr.tsx:1:12
<>{content += '{"hello": "I\'m a button!"}'}</>
~~
Had 1 error formatting.
The wrapper like <> and </> shouldn't be printed, otherwise it's confusing.
