Please see attached patch and let me know if this method is
acceptable. It’s perhaps a little kludgy because sometimes a frame is
created and sometimes it isn’t so we need both methods of ensuring the
initial frame is set properly. This does appear to work for all
scenarios I tested, however.

Thanks,
