Custom CSS won't apply on /admin/books/edit/<id> page

[Himura2la]

I want to hide fields that we don't use from book adding form, for easier adding books.

I put the following custom CSS:

form#bookForm div.form-section > div > div:has(input#data_pubblicazione),
form#bookForm div.form-section > div > div:has(input#ean),
form#bookForm div.form-section > div > div:has(input#issn),
form#bookForm div.form-section > div > div:has(div#curatori_hidden) {
  display: none
}

It does not appear to apply on the page with the bookForm
