Easy "one of" multiple value field state condition

The site is still on 10.2, I wonder if upgrading to 10.3 to get 🐛 #states not working correctly when built from a logical combination of multliple fields Fixed might help?

FWIW I ended up achieving this using an extra container that had the checkbox condition, then the fields inside it had the multivalue condition. It worked, though was a little messy at the CSS layer to make it look correct. But it worked.

My workaround doesn't work properly - dependencies on nested fields are triggered even if a parent field prevents them from being displayed. Argh.

Never mind #4, it turned out to be a problem in our custom code - we had custom validation logic that would set a default value for certain scenarios, I had to change the custom logic to run before the default validation callbacks rather than afterwards, then it worked.

So all good, this workaround seems to be workable for now.
