It's not the best patch in the world but it works.
But it's not applicable for 8.x-1.0-alpha6 so I've prepared patch for that specific version.
I've tried merge request https://git.drupalcode.org/project/viewsreference/-/merge_requests/31 on 2 different projects and it fix works as expected. So I think this is as good as RTBC.

Here is an updated patch to support D10 as well.
Here is working with D9/D10 solution for glossary attachment template:
{% for letter in 'a'..'z' %}
{% set row = '' %}
{{ options.inline ? '<span' : '<div' }} class="views-summary views-summary-unformatted">
{% for loop_row in rows %}
{% if (loop_row.link == letter|upper) %}
{% set row = loop_row %}
{% endif %}
{% endfor %}
{% if row %}
<a href="{{ row.url }}"{{ row.attributes.addClass(row.active ? 'is-active')|without('href') }}>{{ row.link }}</a>
{% if options.count %}
({{ row.count }})
{% endif %}
{% else %}
{{ letter|upper }}
{% endif %}
{{ options.inline ? '</span>' : '</div>' }}
{% endfor %}Fixed.

You have to be sure Leads are enabled.
To do so go Settings -> Open(if not opened) Customize fieldset -> Lead Statuses and click "Enable Leads" there. After that "Leads" link appear in your UI and integration will work.
