Thanks for working on this, @dhruvang21! It works well in my testing, I'm able to drag a new image in the Site Logo block, and I'm unable to do this on trunk. 🎉

I've left one small suggestion, and I also think this PR needs to be rebased with the latest changes on trunk, as I don't think these test failures are related to this PR.

Thanks for the latest changes, they look good to me 👏
