🐛[BUG] BetaSchemaForm use of select with groups

### 🐛 bug description

I have found bug with the selector in a BetaSchemaForm. When i use the selector with an avatar inside. If it is not inside a group object works correctly. But if it is inside i cant see the avatar.
Also if i use a group the fields inside the group dont use all the width of the form but when the field is individual. It use all th width.

### 📷 Code example
Here i have an example in codesanbox:

### 🏞 Expected results
I want to be able to use all the width when i use valuetype group in the column and also i want to be able to add inside this group the field with an avatar without problem

Start with the linked CodeSandbox reproduction and compare BetaSchemaForm selectors used directly with those inside a valueType group. Confirm the grouped selector's avatar rendering and field width behavior; done means avatars render and grouped fields use the available form width.
