1. Click the Someday in the left panel
2. Double click task A in the right panel
3. Change the context from Someday to Inbox and save
4. The task A is still under the Someday context
5. Click any other context and switch back to Someday, the task A is gone.

I think we suppose to have refresh of the Someday context after we change any task of it.

Thanks,
Edward
