Exercism Page Sometimes Doesn't Update on Submit

Sometimes when I submit a solution from the command line, its Exercism page automatically updates, while other times I have to refresh the page first. I just noticed that this behavior is related to another anomaly. That is, when you navigate between pages on the Exercism site, the HTML title sometimes doesn’t update. It’s when the page’s title is out of sync with its contents that the page doesn’t update on its own.
