When switching back and forth between the "following" and "tumblr tv" dashboard tabs, the Show Originals controls element sometimes persists over "tumblr tv." Presumably this is due to the code I wrote to update it firing on new posts, and that dashboard tab not having anything that counts as a post.

I'll deal with this... somehow at some point. Maybe using the navigation hook? Querying for the timeline itself being added? Who knows. It's very minor unless it applies to more than just this scenario.
