The Hovercards Beta Feature (extension Popups) reports an API error when you hover over a link to a Flow board such as Talk:Flow_QA

{"error":{"code":"nosuchsection","info":"Sections are not supported by Flow_QA"}}

The error is expected, but note the info message is missing the namespace prefix.

The error is reported by ApiParse->getSectionContent(). Click the URL above to see it. The $what parameter passed to it doesn't include the page namespace.
