Checking the development database, it looks like the ability to show dropped contexts is on the "things we haven't had a chance to add yet" list. Looks like the support mail you sent in was attached to that item in the database, as well. Thanks!

From what I'm seeing in the database and what I'm seeing on my phone, it doesn't look like the behavior differs across different levels of the tree. We'll show a dropped context while the Edit screen is still active, but if you navigate away from the screen that it's on, it will be hidden at that point.

If you're syncing with the Mac version, of course, the context can be un-dropped and resynced to the phone. Obviously not ideal, but doesn't require reverting to a backup.
