`:not(:has(` and `:has(:not(` are different

[kvtb]

:not(:has( and :has(:not( work differently

actually, only :not(:has( does what is expected, while :has(:not( work exactly as :has(, ignoring the negation introduced by :not(

Can you give an example of each case and show what you expect vs what you get?

I'm trying both cases here: :not(:has) and :has(:not) and they appear OK there.
