Quotation marks converted to entities in rolling back with summary

Question

In the revision history page of an answer, click "edit" next to an old answer, add an edit summary with an apostrophe (') or double-quotation-mark (") in it, and save without editing the post. The software will append "Rollback to revision [number]" to your edit summary (which is fine) and convert your quotation mark to the corresponding HTML entity displayed on the revisions list (which is a bug).

Answer 1

The rollback comments were being html-encoded in the database, which is not how we usually store content.

This will be fixed going forward and I'll work on a fix for the existing bad content.
