 Review comment:
   why use a `StringBuilder` for the `prefix`/`suffix` (also there is a typo in 
suffix)? They only ever contain a single string. This could rather be
   ```
                String prefix = "";
                String suffix = "";
                if (styles.contains(TextElement.TextStyle.CODE)) {
                        prefix = "<tt>";
                        sufix = "</tt>";
                }
   ```
