Other Considerations

There is still a call in libs/model/src/utils/decodeContent.ts that was added in the last few days which I haven't touched.

It doesn't affect thread/comment creation but could cause us trouble in the future: return rawMarkdown.trim();

@raykyri we should standardize how we parse content for canvas/API. As it stands canvas will sign Quill Deltas whereas raw markdown is what is actually stored in the DB so the canvas signed content doesn't match the actual stored content.
