On a page with multiple embeds, the progress bar completes immediately after the first response is received. This means the progress bar reaches 100% and then disappears well before all embeds have loaded and page content is displayed. In this scenario, I would expect the page to be parsed, a queue to be created, and the progress bar to advance some percentage based on the total number of requests in the queue.

Take the Customization page of the docsify-themeable site as an example. The page loads ten separate embeds, leaving the user waiting for a long time with no indication that the page is loading (see #525 for performance related details). Ideally, the progress bar would increase 10% each time one of the ten total requests is complete.
