PrimeNG Button Link stackblitz not working

[shellwe]

Describe the bug

When I go here
https://primeng.org/button#link
and click on the stackblitz example the buttons don't show correctly. It just shows External (but it has an underline) and then a blank button and the first doesn't even show at all.

Environment

Here's a link to the stackblitz, I just went in and hit save to get a URL, I didn't change anything.
https://stackblitz.com/edit/12nfmq?file=src%2Fapp%2Fbutton-link-demo.html

I should add, I tried to copy the code in the documentation into stackblitz but no avail.
