MultiExcerpt Macro content is missing from Page PDF Export

Problem

The customer is trying to export a page to PDF that contains several MultiExcerpt macros (by Appfire) and some of them are missing from the exported PDF file.

Steps to Reproduce

1. Create a page that includes several MultiExcerpt macros (using the legacy or new editor)
2. Setup a PDF stylesheet on the space (this will make the PDF export use the v1 engine)
3. Export it to PDF
4. Compare the PDF export to the contents contained on the page
5. Observe that data is missing (some of the contents of the MultiExcerpt are not included)

Expected Results

All of the MultiExcerpt macro content should be present in the PDF export. 

Actual Results

Some of the MultiExcerpt macro content is missing from the PDF export. 

Workaround

Remove the PDF stylesheet and convert the page to the new editor.
