agenda+ :lang() behavior in Selectors 4

The CSS WG is struggling to button up the details for how "extended 
filtering" works in the :lang selector.

The issue is here: 
https://github.com/w3c/csswg-drafts/issues/8720#issuecomment-4502632427

We should discuss:

- should this be needs-resolution (I think it should)

- should this slip to v5 (I think it can)

- what is the correct behavior here? (I have a separate topic in 
tomorrow's call and there is a long thread above the linked comment that 
illustrates the issues)

- what actions should we take to address?

thanks,

Addison
