In my case, I am able to insert HTML into the Section Title, if it is done through the "Edit topic" page, but not with the quick-edit pencil.
It is currently working in version 3.3 and used to display fontawesome icons.
However, backing up and restoring becomes an issue.
I think there should be an option to allow HTML, similar to "formatstringstriptags" or included in the same setting:
Remove HTML tags from all section and activity names
Uncheck this setting to allow HTML tags in section, activity and resource names.
