Flaky unit test for CodeListPage

[Jondyr]

Description of the bug

One or more unit test in CodeListPage.test.tsx seems to be failing sporadically.

Example of the GitHub action Frontend Test where the unit test fails:

Trace

FAIL libs/studio-content-library/src/ContentLibrary/LibraryBody/pages/CodeListPage/CodeListPage.test.tsx (21.043 s)

Steps To Reproduce

1. Trigger the github action frontend test on a PR
2. Rerun until it fails (in my experience about 50% of runs fail)
