HTMLSanitation in 10.1

I have a number of things added in my 8.5 platform in the HTMLSanitation area. I am working on the upgrade to 10.1 and my configurations are not being used. Based on this documentation page,, it looks like it should still work. 

In 8.5 I have the changes in the communityserver-override file. This document talks about them being in the communityserver file itself. I have tried both without success. I also noted that in an OOTB installation there aren't any HTMLSanitation configuration entries in the communityServer config file. 

Where did this configuration move to? Or what am I doing wrong?
