public bool live_thumbnail { get; set; }
Whether to enable live thumbnail for this page.
When set to `TRUE`, the page's thumbnail in [class@TabOverview] will update immediately when the page is redrawn or resized.
If it's set to `FALSE`, the thumbnail will only be live when the page is selected, and otherwise it will be static and will only update when [method@TabPage.invalidate_thumbnail] or [method@TabView.invalidate_thumbnails] is called.
