background color in Layout Grid Block

Hoping to re-open Zim’s request from a couple years ago with the same Topic Title. I would find a background color control on this block very useful. I tried enabling it with theme.json …

"settings": {
    "blocks": {
        "jetpack/layout-grid":{
            "color": {
                "background":true
            }
        }
    }

… but that doesn’t seem to work.

Thanks!
