Description Jonathan Bedard 2022-09-01 08:53:20 PDT 
The UIKit usage of this API permits public clients to call into `loadObjectOfClass` from the main queue, therefore typically spinning the run loop or using semaphores. As a result, it’ll deadlock due to loadFromHTMLWithData always re-dispatching back out onto the main queue for its callback.

The only way to get around this is to provide a callback queue up front.
