Welcome header text %{site_name} gives error: The following interpolation key is invalid: site_name

The following interpolation key is invalid: site_name

I think “Site_text” is not available. When I try to edit the text at /admin/customize/site_texts/js.welcome_banner.header.new_members?locale=en I can see that only the name is available.

I think site_name is only available for anonymous users. I guess the description needs an update.
