Add patches for field validation when tabs are on edit form

Problem/Motivation

When using Gin admin theme, some field validation errors are invisible.

Steps to reproduce

Not sure if it can be reproduced on a fresh install of Sous, but this is common once you start building out content types.
Add new content and leave required fields blank in a hidden field group (on another tab)

Proposed resolution

Add patches from these issues:
