 #### Refactor TOC Sanitation
 
-* All postprocessors are run on heading content.
-* Footnote references are stripped from heading content. Fixes #660.

+* Footnote references are now stripped from heading content. Fixes #660.
 * A more robust `striptags` is provided to convert headings to plain text.
   Unlike, the `markupsafe` implementation, HTML entities are not unescaped.

+* The plain text `name`, rich `html`, and unescaped raw `data-toc-label` are
   saved to `toc_tokens`, allowing users to access the full rich text content of

+* The value of `data-toc-label` is sanitized separate from heading content
+  before being written to `name`. This fixes a bug which allowed markup through
