I'm using IMAP. Configure your account, so that deleting a message causes it to be marked as deleted. Have at least one deleted and one "not deleted" message in your inbox. Left click the "not deleted" message, it will be shown. Right click a delete message. Actual behaviour: The right click menu for the deleted message will show "delete message". Expected behaviour: The right click menu should show "undelete message". Note that it behaves vice versa, when you display a deleted message, but right click a "not deleted" message (menu will say "undelete", although it should say "delete".) This suggests that the right click menu is built with attributes from the displayed message, although it should use the right-clicked-message.
