When using the full font-stack some the Unicode 1.1 emojis are taken up
by fonts closer up the stack and don't represent the emoji well.

```
font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto,
Oxygen-Sans, Ubuntu, Cantarell, "Helvetica Neue", sans-serif, "Apple
Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
```

 - On Windows, "Segoe UI" -> "Arial" takes over
 - On mac OS, "Helvetia" -> ".SF NS Display" takes over

```

```

 - On Windows, "Segoe UI Emoji"  takes over
 - On mac OS, "Apply Color Emoji" takes over
