Describe the bug / error

In the newer? Microsoft Lists, I cannot click on the group header even though I set defaultClick to headerFormatter in groupProps.

In the older? Microsoft Lists, clicking on a group header with defaultClick set would display a view filtered by the value of that group header.

Steps to reproduce

1. Create a list
2. Create a choice column
3. Create some items
4. Grouping by choice column created in 2.
5. Set the following JSON in the view formatting

Sample Code

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
  "groupProps": {
    "headerFormatter": {
      "elmType": "div",
      "style": {
        "font-size": "16px",
        "cursor": "pointer",
        "padding": "5px 10px",
        "border-radius": "5px"
      },
      "customRowAction": {
        "action": "defaultClick"
      },
      "attributes": {
        "class": "ms-bgColor-themeLighter ms-bgColor-themePrimary--hover ms-fontColor-white--hover"
      },
      "children": [
        {
          "elmType": "span",
          "txtContent": "@group.fieldData.displayValue"
        },
        {
          "elmType": "span",
          "style": {
            "margin-left": "5px"
          },
          "txtContent": "=' ('[email protected]+')'"
        }
      ]
    }
  }
}

Expected behavior

Clicking on a group header with defaultClick set will display a view filtered by the value of the group header, similar to the older Microsoft Lists
