Issue with the "dry run" render

[bretthadley]

Hi,

I guess I have a specific implementation issue but some people might also have similar issue. The frontloadServerRender() calls render twice (first to fill queues then second to get the output) this is causing an issue for me with react-jss SSR (the 2 renders are causing class name conflicts and they generated css from client / server is different because of this duplicate render)

Would it be possible to just pass a boolean to the callback?

frontloadServerRender((dryRun) => { return ReactDomServer.renderToString(....) })

render(true)

my personal use for this is here
