Amazing that anybody would actually put 3rd party API code on the main execution path for rendering their site. What's the best case result? That your website renders correctly after only a 1 second pause?
This sort of widget is best lopped off entirely, or if you think it's absolutely essential, it's something that you load from javascript after all your resources have finished loading and rendering.
Never put your users' experience into the hands of a 3rd party. Other people's code is, nearly without exception, non-debugged, brittle garbage. Wrap it in four layers of try/catch and for the love of jebus, keep it out of your critical path.
