 My theme has a sticky header and there is a 32px empty gap between its top
 to the frame/document top. The admin bar top offset space. To be clear;
 this is when I'm logged in as admin but visiting the site at front-end.
 And yes, I have disabled the admin-bar from the profile page in admin. So
 the expected behavior should be no admin bar but also no blankspace where
 the admin bar would otherwise be.

 I know it's possible to get rid of this blankspace via both codes and CSS.
 But I wanna address this issue since it shouldn't be like this.

 I've been looking around a lot in the core codes. It seems like the /wp-
 includes/css/admin-bar$suffix.css is causing the problem since its' loaded
 even if the admin bar is disabled. And the first rule in that file is:

 {{{
 html {
         --wp-admin--admin-bar--height: 32px;
         scroll-padding-top: var(--wp-admin--admin-bar--height);
 }
 }}}
