It's got to be more than this.

The Family: Man, Woman, Girl, Boy emoji is a ZWJ sequence combining 👨
Man, ‍ Zero Width Joiner, 👩 Woman, ‍ Zero Width Joiner, 👧 Girl, ‍ Zero
Width Joiner and 👦 Boy. These display as a single emoji on supported

Simply copying the sequence in firefox address bar shows me single emoji (I've
NotoColorEmoji Font). This leads me to conclude it's not a font feature
- but a renderer feature.
