 The print styles for Twenty Nineteen include a little snippet meant to
 append the URL to links so it's visible when printed:

 {{{
 a[href^=http]:after {
     content: " < " attr(href) "> ";
 }
 }}}
 Via:

 This snippet is based on recommendations in this article:

 https://www.jotform.com/blog/css-perfect-print-stylesheet-98272/

 In practice, this appears to be fairly unreliable. In testing, @Joyously
 and I only see those URLs sporadically, and haven't been able to pin down
 why.

 If these rules aren't working correctly, I suggest we remove them from the
 theme.
