TypeError: Cannot read properties of undefined (reading 'joypixels')

This has started showing up in our test runs. The only change is updating Node 20 to Node 22. Would you have any idea what would cause this?

```
FAIL src/components/CallDetailPage/Transcript/Comments/CommentsPane.test.tsx
● Test suite failed to run
TypeError: Cannot read properties of undefined (reading 'joypixels')
1 | import Clamp from "react-multiline-clamp";
2 | import { CardContent, Typography, theme, Box, Icons } from "@invoca/titan-core";
> 3 | import { shortnameToUnicode } from "emoji-toolkit";
```

We're using `8.0.0`.
