Add "allow-storage-access-by-user-activation" token to live editor's iframe

It would be great if you could add the "allow-storage-access-by-user-activation" token to the live editor's iframe. This feature would enable several valuable use cases, and I'll describe my specific situation below.

We recently implemented Next.js draft mode but are encountering issues with certain browsers that block cookie storage due to third-party cookie limitations. While cookie permissions can be requested using the API as described in https://webkit.org/blog/8124/introducing-storage-access-api/, having this token is one of the required conditions for the API to work properly. I was able to create a working solution for my use case that functions correctly after manually adding this token to the iframe via dev tools and reloading the editor.
