No, it's not the system ui. You can change it in the `vs\workbench\workbench.desktop.main.js`. Just need replace `:host-context(.OS) { font-family: "Segoe WPC", "Segoe UI", sans-serif; }` in the file.

@blackmann I fixed it [here](https://github.com/blackmann/fonted/pull/3).

@artalar Maybe I'm wrong, but I think it's possible to avoid component type casting. How about that?

@artalar I'm glad to hear that. I've created a PR with an example how it could be implemented. I've changed the props type inferring to provide more clear props type...

It looks like it has been broken in `jsdom` since `24.0.0`. [Release note](https://github.com/jsdom/jsdom/releases/tag/24.0.0) Try to downgrade to the `23.2.0` version. This solution helped me solve the problem.
