Note:
When prefilling the textarea, please add HTML escaped content to the template to avoid any XSS security issues or nesting errors with existing HTML.
Example to escape content in Python:
import html
escaped_html = html.escape(unescaped_html)
Example to escape content in JavaScript:
const escaped_html = unescaped_html
.replaceAll("&", "&")
.replaceAll("<", "<")
.replaceAll(">", ">")
.replaceAll(""", '"');
