 developers about how they determined that this is an issue within
 WordPress Core rather than the plugin, that would be a big help in
 determining how best to resolve this issue.

 Thanks for the detailed response! I submitted a support ticket to updraft
 and they just decided it was a problem the pluggable.php and not anything
 on their end. I kinda think they're full of it but thought I'd post here
 first. They didn't log into the site and try to change anything so I don't
 know how they really came to that decision.
