Inventorio is a mod that changes and enlarges the inventory. As well as that it also adds extra off hand slots. Raised, raises the normal hotbar as expected, but does not the offhand slots.

This looks like it runs into the same issue as #1.

As far as I am aware, the only way other mods can work with this properly is if they render their elements based on whether Raised is loaded.

The other option is that I fix the code in other mods via mixins. This would be on a mod by mod basis. This mod however is written in Kotlin, which is a language I don't know (and I am barely competent in Java), and I don't even know if you can make mixins for Kotlin code.

Well there we go, that wasn't so difficult. I am adding a patch for Inventorio in the next update.
