What:
Add Less.js support for container queries to style descendants of containers based on their scroll state.
This PR also aims to improve function handling for
@mediaand@containerwithout adding new functions to the function registry as was done in #4311.With this solution, future CSS functions should work without having to update Less code.
Why:
Container query scroll state support is available in Chrome 133 (https://developer.chrome.com/blog/chrome-133-beta). Getting ahead of broader support. Without this PR the Less.js output of scroll-state is incorrect.
Global support suggests 65.76% availability per https://caniuse.com/?search=scroll-state.
