Starring and Show/Hide Completed result in duplicate starred items in sidebar and inability to star

Steps to reproduce: 

1. Start at a starred node with completed items hidden. Observe the Star and that the node appears in the Starred list in the sidebar
2. Hit Command-O to display hidden items. Observe that the Star disappears (bad) The node remains in the sidebar (good)
3. You can hit Command-O again, but neither of these two things changes. The star is still not displayed, but the node remains in the sidebar
4. Hit the Star button again. Observe that the star is not displayed, and there is now a duplicate listing of the entry in the sidebar. You can repeat this as many times as you want to get many multiple listings in the sidebar. The star will not display.

Refreshing sometimes removes the sidebar duplicates and sometimes doesn't, depending on whether the item is actually starred or not when you refresh.
