@magento-engcom-team I am experiencing this same issue on Magento 2.2.3. Glad to hear it's going to be fixed in a future release. Can you share a link to the commit?

@ALL - I had a role that had "Customers" selected, but I got an error when loading customer in the backend. I had to select these two additional items before I could get the customer to load in the admin:

Presumably it's because there are "Product Reviews" and "Newsletter" tabs/blocks on that page:
