I have successfully tested this PR, thanks @bembelimen as always.

I created/edited Categories in Articles, Banners, Contacts, Newsfeeds, and weblinks (which I added for this testing), and played around with as many settings as I could after PR applied and it all seemed to work as expected!

@bembelimen Do you have an idea why system tests are failing here with an error which seems to be related?

Running:  api/com_banners/Categories.cy.js                                             (98 of 150)

     CypressError: `cy.request()` failed on:

https://localhost/cmaria/api/index.php/v1/banners/categories/33

The response we received from your web server was:

  > 400: Bad Request

This was considered a failure because the status code was not `2xx` or `3xx`.

If you do not want status codes to cause failures pass the option: `failOnStatusCode: false`
