I am just checking wordpress.org on mobile and I have found the top Register & Log In menus don't show on mobile and the top design breaks.
Please check the below Add video URL for a better understanding.

This appears to be the combinations of 2 things:

1. We don't use the global header footer which has code to show the admin bar on mobile and styles the dropdown:

​https://github.com/WordPress/wporg-mu-plugins/blob/trunk/mu-plugins/blocks/global-header-footer/postcss/header/admin-bar.pcss

2. These admin-bar styles being applied:

.admin-bar {
    position: inherit !important;
    top: auto !important;
}

We have a couple of choices to fix:

1. Some throwaway admin-bar CSS styles added to the wporg-gutenberg theme.
2. Load the global header styles but do not have the header show up (it does not have this functionality yet). This would be the preferred approach because the admin styles would match other parts of the site.

3. Hide the admin bar completely on this page.
