Site Address (URL) in network/site-info.php for primary site always prefixed http://

[bobbingwide]

While switching a WordPress Multisite network to https, I noticed that on Edit site for the primary site,
wp-admin/network/site-info.php?id=1, the Site Address (URL) field was displayed as http://example.com even though I was using https:// to access the site.

I would have expected it to be https://example.com

Explanation

esc_url() assumes the ​http:// if the URL doesn't contain a scheme.

Proposed solution

Use logic similar to that in network_home_url().

Simple solution would be to wrap esc_url() with set_url_scheme()

echo set_url_scheme( esc_url( $details->domain . $details->path ));
