I would love for this to be moved to chrome/browser/guestview/webview.

If (WebViewGuest::FromWebContents(web_contents)) {
  return new WebViewMenuContext(render_frame_host, params);

}

Done.

+  if (chrome::IsRunningInForcedAppMode())
+    return new MenuCategoryAppMode(render_frame_host, params);
+
+  const extensions::ViewType view_type = extensions::GetViewType(web_contents);
+
+  if (view_type == extensions::VIEW_TYPE_APP_WINDOW)
+    return new MenuCategoryPlatformApp(render_frame_host, params);
+
+  if (view_type == extensions::VIEW_TYPE_EXTENSION_POPUP)
+    return new MenuCategoryExtensionPopup(render_frame_host, params);
+
+  if (view_type == extensions::VIEW_TYPE_PANEL)
+    return new MenuCategoryPanel(render_frame_host, params);
+
+  return new MenuCategoryBase(render_frame_host, params);
+}
