emoji has wrong colors

[alisonatwork]

Describe the bug

Some emojis end up with incorrect colors. It does not matter so much for certain emojis, but for other emojis like flags it can end up be quite confusing.

Steps To Reproduce
Steps to reproduce the behavior:

1. Start writing a mail
2. Paste an emoji like 🇺🇦 (shows up correctly in compose window with native Thunderbird dark mode)
3. Send it to yourself
4. View emoji (shows up incorrectly with Darko enabled)

Expected behavior
I expect emojis not to have their colors changed.

Device info:

• operating system: Windows 11
• Browser and version: 102.3.0
• addon version: 3.0

Additional info

Also curious where the source code for this addon is. This one is faster, cleaner, less ad-ridden and requires less permissions than the other dark mode addon for Thunderbird, so I would prefer to contribute to it.

In case anyone else is reading this issue and has the same problem, I ended up writing my own dark mode add-on that solves the problem of inverted color emojis. It's a tiny implementation (<50 lines), but the code is all open and should be easy to modify to fit your needs if you want something a bit different: https://github.com/alisonatwork/donker
