Describe the bug / error

Even if hideSelection is set to true, the group header can still be selected. Additionally, when this setting is applied, the group header shifts to the right, causing the layout to appear broken.

Steps to reproduce

1. Group by any column in any list

2. Apply the following JSON to the view formatting

   {
     "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
     "hideSelection": true
   }

Expected behavior

If hideSelection is set to true, group header will not be selectable either.

I can confirm these bugs from my side. Regarding the header shifting to the right (bug confirmed too), I'm using a workaround: the first column should be the OOTB "Type" one, so that the shift to the right will be minimal.
