Favicon option in white branding for the web browser's tab

As a developer, I want to customize the favicon in the browser's tab when white-branding the SPanel admin interface. As you know, there is an option to use a custom logo instead of SPanel default logo. But after using that option,  the SPanel favicon is replaced by a black and white globe in the browser's tab. There is no option to upload a custom favicon to replace the default black and white globe. To me, this is an important part of white branding. Is there any way you can fix that so it can be reflected in the Admin and User interfaces?
