Describe the bug / error

Command bar formatting is not working in document libraries with new modern UI.
Command bar formatting is done using customizations through commandBarProps.

Steps to reproduce

1. Open view format settings.
2. Add JSON to hide few default buttons:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
  "commandBarProps": {
    "commands": [
      {
        "key": "new",
        "hide": false
      },
      {
        "key": "newFolder",
        "hide": false
      },
      {
        "key": "newWordDocument",
        "hide": false
      },
      {
        "key": "newExcelWorkbook",
        "hide": false
      },
      {
        "key": "newPowerPointPresentation",
        "hide": false
      },
      {
        "key": "newOneNoteNotebook",
        "hide": false
      },
      {
        "key": "newFormsForExcel",
        "hide": false
      },
      {
        "key": "newVisioDrawing",
        "hide": false
      }
    ]
  }
}

4. Open the view

Expected behavior

• Button section "New" should be hidden in command bar - FAIL (all butons are visible).
