The problem is that the user experience is not "oops, I accidentally flagged an article, I should go unflag it."

The experience is more like "I clicked on a link to an article, but instead of loading the article, the HN page just reloaded. Now I have to scroll down to find it again... Hmm.. Where is it? Maybe it's moved to a different page...? What was I even looking for again? Oh well"
