REGRESSION (r271493 ) Crash in +[NSAttributedString(WKPrivate) _loadFromHTMLWithOptions:contentLoader:completionHandler:] on background thread

This method is meant to be thread safe by dispatching background thread work back up to WebKit's main thread.

If called before Webkit is initialized on the main thread, it gets it wrong.

Restore this call site back to dispatch_async to fix.
