Can mdxJsxFlowElement have phrasing content as child?

[clemyan]

I am currently writing a markdown plugin in TypeScript to process MDX and have encountered a problem:

• If I enter <div>Hello <span>World</span></div> into the playground to check the mdast tree, we can see an mdxJsxFlowElement having mdxJsxTextElement and text as children.
• But neither the spec nor the TypeScript types allows mdxJsxTextElement and text to be children of mdxJsxFlowElement

So which of the two is correct? Or am I missing something?
