1. I went through each individual permission removed from `getRolePermissionBlobs` in D13017, and making sure the admins had it. In most cases this was already covered, as an older iteration of the permissions system required admins to have all permissions listed explicitly. However, when `REACT_TO_MESSAGE` and `EDIT_MESSAGE` were introduced, we were able to give them to both admins and members by adding them to `getRolePermissionBlobs`; as such, these had never been added for admins to `getRolePermissionBlobsForCommunityRoot`.
2. In combination with later diffs (including an updated migration), I will test to make sure that [ENG-9026](https://linear.app/comm/issue/ENG-9026/emoji-tooltip-doesnt-show-up) is resolved, and my keyserver admin can react to messages in a non-GENESIS community. (Fixing GENESIS will require some additional work, to be covered in later diffs.)
