well it's nice to hear that this problem still exists in 12c - i'm very aware of it in 11.2.0.3
it's because the software isn't really able to handle the standby log which is currently active. i have run into the exact same issue doing a "recover datafile" on a clone which was created using a backup controlfile from the standby. in my case, i simply used the backup from the primary (and changed nothing else) and i don't have the issue.

So you did also try taking a backup of the primary controlfile and restoring this into the standby, then renaming all your logfiles and datafiles to match the new locations? That has worked for me on 11203 for avoiding the error you mentioned above.
