Items Being Marked Read Automatically

I’ve noticed, beginning yesterday and continuing today, that sometimes on the web app, while I’m reading stories, that some of my unread feeds disappear without me doing anything. The first time I happened, I thought maybe I had misremembered which feeds had unread articles, but once I started paying more attention, I saw it happen. A feed had an unread story, and then it just disappeared from the list. If it matters, I am using the latest developer version of Chrome on Windows 7, but I also have seen it on the dev channel Chrome in OSX. My Newsblur username is CMcKinnon.



This is still happening. Am I the only one seeing it?
