This is a strange dependency, runs counter the comment above.
The content stuff should be exposed from 'public' part of the tree.

This is leftover cruft from an earlier try, removed.  I also checked for other
leftover code, but didn't find any.

Here I use CONTENT_EXPORT for the MHTMLGenerationManager class to make the
StashMHTMLPartForAdditionToPage() method available as a public symbol.
