"Grant all users permissions for this space" ignores custom content types (Free plan)

Hello,

On free plan, users have “Grant all users permissions for this space” option available in space settings. The problem is, this action ignores custom content permissions from “Add-on” tab. They are disabled for all users even after applying this action (except of space creator).

This problem makes my app unusable for users having “Free plan” as I’m creating add-on that relies on custom content type. Is there a way to grant custom content permissions for all users as well or this is a bug?
