I was mistakenly thinking that you can define variables in beforeEach, but it turns out these are not used.
Rather, Jest was automatically creating variables for the elements according to their IDs. How convenient!
I couldn't think of a simpler way to hardcode it, so now we have a clever generic method :)
We can assume that hidden elements will stay hidden, but we need to check each time if an element is disabled or not.
I'm starting to think that these stimulus tests are worthless. The environment is not the same as a browser, which creates extra work to deal with the inconsistencies. And it means we're not testing real world behaviour.
So these are just unit tests, but they take extra effort to put together due to the inter-relatedness with the DOM. Hmm.
