contentRaw is not persisted, we should probably use "local state" for it.

The only differences I'm seeing are in some <p>\u00a0</p> and some ; missing/being added to ends of inline style attributes.

Storing the raw content without any processing seems like a bad idea? Why should this be different from the classic editor?

content: editor.getContent(),
} );
return false;
