WorkFlowy is rewritten in React

In December 2018, Workflowy was rewritten by the core team in React.

This supposedly was a good thing; a better, more modern framework and architecture would make WorkFlowy better for everyone. Hurrah!

Whilst they did a great job in keeping things largely the same, one annoying problem began to rear its head: the browser's "find" functionality didn't work because React implemented rendering optimisations which resulted in offscreen text not being rendered.

Argh! Not much to do at this point, but hope they fix it.
