[csswg-drafts] [css-forms-1] Ensure ::picker() options are always reachable on small viewports (#13526)

nt1m has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-forms-1] Ensure ::picker() options are always reachable on small viewports ==
After doing some testing for various customizable select demos on mobile, @smfr found that the options were not reachable on mobile on long selects (take the color select from https://codepen.io/argyleink/pen/wvYrZEV for instance), which is an usability regression from the native select.

I suggest adding this to the UA sheet:
```
::picker(select) {
  max-height: 100vh;
}
```
(not sure if it should be dvh/svh or vh)

This seems to make the picker limit its height to the viewport to which point you can scroll within the picker.
