Greetings — I see under User Role Editor settings > Multisite that I can check “Enable ‘unfiltered_html’ capability,” but I don’t know whether this capability then applies only to role = administrator; does it? (That’s our desired restriction.) I can’t see the unfiltered_html capability listed under core capabilities per role, so it doesn’t appear to be an editable capability per role.
Excuse me for delay with answer.
You don’t see the unfiltered_html capability at the list of core capabilities as URE marks it as the “deprecated” for multi-site. Turn on the “Show deprecated capabilities” checkbox and you will see it.
The option “Enable ‘unfiltered_html’ capability” force this capability to work. It will work for those roles only, which include it. That is if you have ‘unfiltered_html’ capability turned on for the “Administrator” role only it will work for the “Administrator” role only.
