className not working?

I have a simple `...`

Everything works great except generated html is `` . Instead of `class="table table-condensed"` it remains lower case `classname`.

I don't see a correct way of using it in documentation

Edit: I just did a string replace to get through it but I was still wonder if I'm missing anything

Reproduce the reported table conversion in the repository using a React element with className="table table-condensed". Trace the JSX-to-string handling for the className prop and verify that the generated HTML uses class="table table-condensed" without requiring a caller-side string replacement.
