No critical issues found.

Notes

• I don't know why you're using the header element here. Generally, it's okay, but please be aware that if this component is used outside landmerks (header, main, footer, article, section, etc. elements) the header element of the component turns into a banner landmark for the entire page.
• According to the spec, role=button is not allowed on header elements.

Best Practices

• Don’t make summaries too long in expandable quickfacts because they’re used as the label for the button.
