Bug: JavaScript in HTML export not recognized by LibreJS as free [9.4.5 (9.4.5-16-g94be20-elpaplus @ /home/jorge/.config/emacs/elpa/org-plus-contrib-20210412/)]

Hi.  The HTML export has JavaScript that LibreJS does not recognize as
free.

My first attempt at an workaround (inspired by the Org Mode mailing
list) was merely encoding the ampersand in the magnet link, but that
*did not make LibreJS happy*.  Then I checked LibreJS manual and saw
this excerpt:

https://www.gnu.org/software/librejs/manual/librejs.html#Free-Licenses-Detection-1

    Public domain is not a license (see
    https://www.gnu.org/licenses/license-list.html#PublicDomain).  If
    you want to release your work to the public domain, the FSF
    recommends using CC0.

Then I came up with a successful workaround.  I included the following
code in my Org Mode customization file:

;; [2021-04-16 sex]: HACK Work around a bug that confuses LibreJS
(with-eval-after-load 'ox-html
  (setq org-html-scripts
        (string-replace "\
// @license 
magnet:?xt=urn:btih:e95b018ef3580986a04669f1b5879592219e2a7a&dn=public-domain.txt
 Public Domain"
                        "\
// @license 
magnet:?xt=urn:btih:90dc5c0be029de84e523b9b3922520e79e0e6f08&dn=cc0.txt 
CC0-1.0"
                        org-html-scripts)))

This works; it makes LibreJS happy.

Thank you for your work in Org Mode!
