Beaver Builder will automagically revert content to a "native" state without short-codes, etc. if the builder is disabled. This ensures a page's content is always pure should someone change their mind about leveraging the builder.
Presently DIVI makes a mess of a site with all manner of shortcodes. And if you disable DIVI all the edited content is lost.
So... how does Upfront Builder handle content if disabled? Will it be riddled with short-code or will it render a "clean & sanitized" version of the content?
