Two Column component width dropdown gets blank after changing width

Definitely a bug! 👍 Thanks! 🙏

This is either a bug on the back-end or in the Redux-integrated field widgets. Can you please attach the request body that was sent to generate that form? 🙏

After drag and drop Two Column component :

    "layout": [
        {
            "nodeType": "region",

I created another issue which is likely a duplicate of this.

Can we add/expand an e2e test for this?

This is certainly a stable blocker, but feels like it causes enough brittleness/distrust that it should be a beta blocker?

Clarifying issue title.

I don't think we should block the release on this but we should try to get this fixed regardless.
