[snap] emoji show as black and white if fonts-symbola is installed

[Jeremy Bícha]

I'm using the Chromium Snap from the Beta channel.

Test Case
=========
0. Be sure you don't have the Chromium deb running.
1. Visit https://launchpad.net/bugs/1779569
The rainbow emoji 🌈 should show in color
2. sudo apt install fonts-symbola
3. Close Chromium. Wait a few moments to make sure it closes then open it and repeat step 1
4. The rainbow emoji 🌈 shows in black and white

Other Info
==========
Firefox and GTK apps like gedit correctly show 🌈 in color as long as fonts-noto-color-emoji is installed, regardless of whether fonts-symbola is also installed.

I also was unable to duplicate this bug with the Firefox Snap [edge channel 63.0b9-1 (134)].

System Info
===========
Ubuntu 18.10

What distro version are you building the Snap from? Maybe you need fontconfig from bionic?

[Olivier Tilloy (osomon)]

Indeed the snap links against and contain libfontconfig.so.1.9.0, from xenial.

[Olivier Tilloy (osomon)]

The snap is now being built on bionic. However the issue can still be observed. What's more, it's not snap-specific. The deb is similarly affected.

I have issue with this on ubuntu 20.04 focal, I have setup the color emoji for chromium and another program for using.
Once I update to 20.04 and it using snap version of chromium, It turn back to black and white emoji which is quiet annoy me for spending time to debugging it and find out that is snap version causing it.

I have turn the chromium-browser back to deb version and it all back to normal.

Here's a quick fix:

sudo apt remove fonts-noto-color-emoji
sudo apt install fonts-noto-color-emoji

Still an issue? Cannot reproduce in current stable 107.0.5304.87.
