Has anyone been able to get Copy and Pasting Block Items between Block Grid and Block List working? I'm assuming:

@inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage<Umbraco.Cms.Core.Models.Blocks.BlockGridItem>

and

@inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage<Umbraco.Cms.Core.Models.Blocks.BlockListItem>

are not interchangeable.
