Multisite: Users without a role are not returned in sub-site search results

[travisanderson99]

We recently came across this issue after migrating off WooCommerce. Our default role was the 'Customer' role provided by WooCommerce. When WooCommerce was removed from our sites, that role was subsequently deleted - leaving a large percentage of users without a role.

Generally this would not be an issue, but users without a role are not returned in the search results on a multisite sub-site.

I am able to find the user by searching by name or email on the parent site, and the sub-site is also listed under the user's sites, but they don't display in search results without a role. This makes it very difficult to find or edit a user on the sub-site.
