DataGrid scroll bars work but NOT visible

All the configurations, look correct. Definition below. Wondering what prevents the scroll bars from being visible, yet functional. I tried using 'style' with height/width with no effect as fyi. Any help would be appreciated.

    <RadzenDataGrid  @ref="grid" IsLoading=@isLoading Count="@count" Data="@terms" LoadData="@LoadDataGrid" AllowSorting="true" AllowColumnResize="true"  AllowFiltering="true" AllowPaging="true" PageSize="15" TItem="ProviderTermRawDataVM"  FilterMode="FilterMode.Advanced"  ShowPagingSummary="true" LogicalFilterOperator="LogicalFilterOperator.Or">
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="ID" Filterable="false" Title="ID" Frozen="true" Width="100px" TextAlign="TextAlign.Center" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="ProcessedStatus" Title="Process Status" Width="240px" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="TaxID" Title="Tax ID" Width="170px"/>
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="NPI" Title="NPI" Width="170px"/>
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="FirstName" Title="First Name" Width="170px"/>
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="LastName" Title="Last Name" Width="170px"/>
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="IsError" Title="Error" Width="100px"  />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="FacilityName" Title="Facility" Width="200px" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="Address1" Title="Address 1"  Width="450px" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="Address2" Title="Address 2"  Width="240px" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="City" Title="City" Width="200px" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="State" Title="State" Width="100px" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="Zip" Title="Postal Code" Width="140px" />
            <RadzenDataGridColumn TItem="ProviderTermRawDataVM" Property="TermDateRaw" Title="TermDate" Width="140px" />

Most probably the DataGrid is in overflow:hidden container - use your browser tools to check it.

Interesting. If I change the below css to 16px the scrollbar then shows up. Resolution is 1920 x 1080 on display. Any ideas why the 8px doesn't show?

::-webkit-scrollbar {
    width: 8px;
    height: 8px;
    z-index: 1;

We've tested on various Mac configurations however everything worked normally. You can remove the scrollbar styling completely if you want:

I've had the same issue on a desktop app running in WebView2. Tracked it down to the border setting of the scrollbar:

body:not(.rz-default-scrollbars) ::-webkit-scrollbar-thumb {
  background: rgba(141, 142, 144, 0.5);
  border: 4px solid rgba(0, 0, 0, 0);
  background-clip: padding-box;
  border-radius: 8px;

The 4px transparent border causes an 8px width scroll bar to be rendered as hidden. The scroll bar is only visible if the border is assigned a colour or if the scrollbar width is increased to greater than 2 x the border width.
