UFT 12 does not recognize HTML elements in a webview of a WPF application ...

UFT 12 does not recognize HTML elements in a webview of a WPF application . In my case, I have a WPF application and it Within the webview que opens in WPF application tabs, and the UFT only recognizes the HTML elements in the first tab. It may be a limitation of the UFT or some problem in WPF application?
