As a French Wikisource user, I want the cover page bug to be resolved, so that I can see the cover page properly displayed in all file formats.
**Background: ** French Wikisource exports have a unique feature -- they display an image of the book's cover on the first page (see screenshot example below). This allows users to have an enriched experience for users. However, there is a bug -- the first page is blank (rather than an image of the book's cover). Users have reported this issue occurring for PDF downloads, but I have also been able to reproduce a version of the issue for EPUBS as well (i.e., the cover image is not shown, but there also isn't a blank page as a first page). Overall, the purpose of this ticket is to try to fix the issue, so that all major file formats provided to users -- PDF, EPUB, and MOBI, at the very least -- display the cover image when a book is being exported.
**Acceptance Criteria:**
* Investigate issue of cover page images not appearing in PDF and EPUB exports
* If possible, propose a solution or implement the solution
**Visual Examples when downloading [[ https://fr.wikisource.org/wiki/Une_Visite_%C3%A0_Bedlam | Une Visite à Bedlam ]] from French Wikisource:**
//Cover image displayed in MOBI export of book//

// First few pages of PDF: Cover page blank in PDF version of same book//
