What was the result of your investigation into whether checking
Browser::host_desktop_type() is necessary?

Didn't get to it yet, but doing so after I upload the next patchset.

   bool is_browser_fullscreen = url.is_empty();
   if (ash::switches::UseImmersiveFullscreenForAllWindows())
     return is_browser_fullscreen;
   else
     return is_browser_fullscreen && IsBrowserTypeNormal();
 #else
   return false;
 #endif
 }
