Replace Aloha Editor #1
Description
We use the Aloha Editor for rich text. Unfortunately it's not well maintained anymore, plus modern rich text editors rarely use HTML as the persisted state (model) anymore. So there are few upgrade options, notably Squire, which explicitly maintains an HTML model to support rich text emails (which are a wild west of HTML). If we want to go full modern consider Quill, but then handling existing presentations becomes tricky.
