Web Browser Error for VIVE Focus(Andorid) VR in Widget 3D

When you compile a project with a 3D widget using WebBrowser for Vive Focus, an error occurs. The 3D Widget is anchored to the camera without saying anything. This does not happen with a normal 3D Widget, it only happens when using WebBrowser. This is a problem for me. Is there any way to fix it? Solution is expected in the next versions of Unreal. Is it a problem of the CEF version for Unreal? The widget is anchored to the VR camera. Could you obtain your material even if it appears anchored to make it disappear and introduce that material in another mesh, for example a plane? But I can not get its dynamic material because the widget does not exist …Please any help will be more than appreciated.
