Edited draft comments are logged with old text in review history

When draft comments are edited and saved as public comments at the same time, review history gets updated with the old (draft) comment text.
To reproduce:

• create draft comment in review, e.g. "draft comment"
• click edit, change the comment text (e.g. "public comment"), click "Comment" rather than "Keep as Draft" to have the comment updated and published at the same time
• expect to see updated comment text on review page
• but when looking into Review History, you would notice "added comment" action with old comment test (i.e. "draft comment" rather than "public comment") - that's wrong.
