When viewing a TinyMCE page, or when a Fabric page's content is rendered in the "view" format, different colors are used for highlighted text.

The color difference is most noticeable for yellow highlighted text.

Steps to reproduce

1. Create a new Fabric page with highlighted text.  Publish it.
2. Publish a 2nd version of that page.
3. Go to the "Page history" screen.
4. View the 1st version of the page.
5. Since old page versions are rendered with the "view" renderer, the highlighted text will have slightly different colors than when that version was the current page version.
