bug#70444: Broken Emoticons in Browsers

[Dr. Arne Babenhauserheide]

Hi,

for more than a month now many emoticons are broken in my browsers.

An example is https://www.draketo.de/wissen/klimalinks.html
I see ⚠, but I cannot see 💡 (though copying it into an Emacs buffer
shows the icon).

Also Flags like 🇬🇧 and 🇩🇪 are broken.

I have a huge number of fonts installed (list at the end), so this
should actually work.

I attached a screenshot from icecat which shows the problem;
ungoogled-chromium has it, too. Firefox installed via flatpak works,
though (second attached image).
