Describe the Bug

When using experimentalReactChildren, self closing tags break. If you use any void tag (such as hr or input) inside of a react component, you get the error:

(...) is a self-closing tag and must neither have `children` nor use `dangerouslySetInnerHTML`.

What's the expected result?

Self closing tags should be preserved
