Comment (by rajinsharwar):

 Hi @kitchin, thanks for the test instructions. Your 2nd patch does seem to
 solve the issue and address this behavior, on the single-site
 installation. I didn't get a chance to test this on the multi-site today,
 but if someone can share if it addresses the issue, we can get this merged
 sooner.
