Unhandle exception crash the application

Bug Report

An "unhandled exception" cause the full application crash. The configuration include a requester and also allow javascript execution.

var requester = new HttpClientRequester(httpClient);
var config = Configuration.Default.WithRequester(requester).WithDefaultLoader(new LoaderOptions { IsResourceLoadingEnabled = true }).WithJs();

But a network issues cause the app crashes. Looks like the request occurs in an isolated thread and the program can't catch the exception.

Stack Trace:

It should definitely be handled.

Mind trying to do a PR on this? Many thanks for reporting! 🍻
