RDS web client thumbprint does not match

A well known and very frustrating problem exists with the RDS web client. Every year when our certificates renew we need to clear the cache of every user in order for the new certificates to become valid. PLEASE can MS update the cache control on the web client html pages and stop it from caching the cert values

It is raised in lots of places including here Remote Desktop Web Access HTML5 certificate error after replacing - Page 2 - Microsoft Community Hub

Please fix it
