I think I remember this being required to make sure the DW iframes render correctly based on dropdown, are you getting a bad user experience using 'key'? How does that differ from 'if'?

Discussion on Slack: throwing error with key

Posting this for posterity: @benkates {#if} seems to work just as well for the simple examples, but not as well for the one wrapped in the loader. there we might need both. I'm pushing the results of my experimentation here after chatting with @aleszu.

I also noticed a few places where the code example strings differed slightly from the actual code in the story and synced everything up a bit more.
