PDF Reader is not loading properly.

Problem/Motivation

I have created 4 to 5 article pages, and in them, I am rendering PDFs using a PDF reader. However, after opening 2 or 3 articles, the PDF does not render on the 4th article page. I have used the Google Viewer renderer.

Steps to reproduce

1. Add a field of file type and select PDF reader as a format.
2. Upload a pdf file and save the content page.
3. Open 3 to 4 content pages and on the 5th page the pdf will not render. (Refer image).
