[Bug-gnuzilla] LibreJS: even when whitelisted, tv.nrk.no does not play

[Marco van Hulten]

Hello—

When I try to watch a video on https://tv.nrk.no/, LibreJS blocks the
non-free JavaScript that is apparently needed in this website.  When I
whitelist tv.nrk.no in the configuration, LibreJS does not complain,
but the video does not play (also when LibreJS is the only add-on
loaded in IceCat).  Only if I disable the LibreJS extension, videos on
https://tv.nrk.no/ will play properly.

My first guess is that there is an attempt to run JavaScript from a
third-party domain, but if that were the case, why would LibreJS not
show a message about that?

This happens with IceCat 52.3.0 on both GuixSD and Parabola, as
provided by the respective distributions.  LibreJS 6.0.13.
