Console error `:first-child` unsafe

[maarteNNNN]

Description Getting an error in the console:

The pseudo class ":first-child" is potentially unsafe when doing server-side rendering. Try changing it to ":first-of-type".

Reproduction

Steps

1. Clone https://github.com/maarteNNNN/wysimark-quasar-test
2. Run with npm run dev
3. Open the page
4. Open the console
5. The error should be visible on load

Expectation It shouldn't throw the error.

Environment

• Wysimark Version: "@wysimark/vue": "^3.0.3"
• Operating System: Fedora Linux Workstation 38
• Browser: Brave (Chrome-based)

Thanks @maarteNNNN

For clarity, this is more like a warning from the emotion CSS library.

I will figure out a way to silence it but it doesn't seem to actually harm formatting the way we use it and the recommendation to switch to :first-of-type happens to be not valid for our use case unfortunately.
