I think that Fl_Help_View uses Fl_Shared_Image to wrap the loaded GIF file, and when the Help_View is redrawn, it's draw method then uses either; - Fl_Shared_Image::get() to fetch the image the first time -or- - Fl_Shared_Image::find() to fetch the image on any subsequent time. So, I *guess* that Fl_Shared_Image::find() simply returns a reference to the image that was loaded by that first call to ::get(), and that maybe is why you don't see the image animate. I don't know enough about this to suggest a way forward, however...
