There was a problem hiding this comment.
This breaks again in Node 23, but ok, let's worry about that later

In React 19,
StrictModewon't double-call effects on initial mount unlessStrictModeis at the root of the app. Our previous way of enablingStrictModecreated aWrapper, meaning that theWrappercomponent was at the root of the app, resulting in the double calling of effects not happening in initial mount in React 19.This PR uses the new property
reactStrictModefrom@testing-library/reactto enable double-calling on initial mount in React 19 tests.This option was introduced in this PR, that's why I also upgraded the dependency.
This PR also changes some tests. In the ones I was most confident, I actually updated the assertions. For the ones I wasn't, I disabled strict mode for that particular test in React 19. If you know how to fix it, please let me know 😄
