The following domains are excluded from having the external site icon in the theme css:
main a[href^="https://loc.gov"]::after,
main a[href^="https://www.loc.gov"]::after,
main a[href^="https://staff.loc.gov"]::after,
main a[href^="https://blogs.loc.gov"]::after,
main a[href^="https://libraryofcongress.github.io"]::after
For the AI Framework, many of the links point to the labs.loc.gov subdomain.
I propose adding the following to the style.css
file, if you agree:
main a[href^="https://labs.loc.gov"]::after
As before, happy to do a PR for this, but wanted to make sure of the process before I do that.
