[toy-crane]

Describe the bug
i`m using typescript with theme UI
MDX seems to does not recognize react fragment <></>

To Reproduce
use fragment tag <></> in mdx component

Expected behavior
mdx return @jsxFrag pragma is required when using an @jsx pragma with JSX fragments.ts(17017)

Additional context
work around solution is that using React.fragment
is there another way to fix it?

Thanks for the issue, @toy-crane!
