Cell Context Menu not working in .net maui

when u create a .NET Maui Blazor app and try to use a CellContextMenu on a DataGrid. It does not work. u get the error 'WebViewNavigationManager' has not been initialized.

I figured out that the problem comes when u inject the ContextMenuService.

This is needed for ContextMenu to work properly:

          /// <summary>
          /// Gets or sets the navigation manager.
          /// </summary>
          /// <value>The navigation manager.</value>
          NavigationManager navigationManager { get; set; }
          
          /// <summary>
          /// Initializes a new instance of the <see cref="ContextMenuService"/> class.
          /// </summary>
          /// <param name="uriHelper">The URI helper.</param>
          public ContextMenuService(NavigationManager uriHelper)
          {
              navigationManager = uriHelper;
          
              if (navigationManager != null)
              {
                  navigationManager.LocationChanged += UriHelper_OnLocationChanged;
              }
          }
          
          /// <summary>
