Salesforce Summer '21 release notes say that the default font is going to be the System UI font, and Salesforce Sans is no longer used

Hi everyone,  

Salesforce Summer'21 release note says - Salesforce Sans is no longer supported and OS default font will work. 

Lightning-rich-text still have 'Salesforce Sans' in the list, and this is creating a problem. So what could be the exact solution for this?  

I really need help for this to resolve my issue. 

Thanks, 

Brinda
