From a quick look, every failure is expected, and no harm
We only need to adapt/relax the tests

@topdev658, please don't use ChatGPT to answer. The same as in another issue: #13221 (comment)

[Girgias]

@jorgsowa ChatGPT provides a good solution sometimes. Why I don't use it? Has it any problems? Or just don't like?

ChatGPT does not check its answers to know that they are factual. And it will routinely say nonsense and waste time.

So yes it has massive problems and do not use it to respond or provide "info" on this bug tracker.
