 Subject: extend ApplyWebPreferences with Electron-specific logic
 
-background_color can be updated at runtime, as such we need to apply the
-new background color to the WebView in the ApplyPreferences method.
+On macOS, popup menus are rendered by the main process by default.
+This causes problems in OSR, since when the popup is rendered separately,
+it won't be captured in the rendered image.
+Offscreen can be updated at runtime, as such we need to apply the
+turn on/off ExternalPopupMenu in the ApplyPreferences method.
 There is no current way to attach an observer to these prefs so patching
 is our only option.

 done in future work.
