View Transition pseudo-elements with pseudo-class marked as invalid

[chriskirknielsen]

Hi there,

I've started playing around with the View Transition API, which allows selectors that are a little novel, such as ::view-transition-group:has(::view-transition-new(*):only-child).

However, when trying to run minification on my styles, an error is thrown:

Invalid pseudo class after pseudo element, only user action pseudo classes (e.g. :hover, :active) are allowed (via SyntaxError)

Here is a simple demo to reproduce it:

::view-transition-new(*):only-child {
	animation-duration: 500ms;
}

The parser would seem to need new logic to allow pseudo-classes attached to pseudo-elements as this is now a valid use-case.

Thank you!

I'm seeing similar issues with the :disabled pseudo-class (https://developer.mozilla.org/en-US/docs/Web/CSS/:disabled)
