Steps to reproduce the problem:
Internals>Plugins>PDF

If the browser window is sufficiently tall that more than one page would be displayed in the window in the initial view, many multi-page PDF files will instead only display the first page and not subsequent pages. If however, the window is resized such that only the first page or a portion thereof would be displayed, the user can scroll down and view all pages of the document.

In both cases the page count in the top navigation bar displays the correct number of pages.

In the case of error, a small drop shadow "dot" is visible beneath the first page where the content for subsequent pages would presumably have rendered. There is one drop shadow "dot" per PDF page.

A PDF file reproducing this behavior in Chrome 50 is attached. A monitor with sufficient vertical resolution is required to reproduce this bug. A vertical window size of 1440px is sufficient to cause this file to produce the bug.

What is the expected behavior?
In chrome 49 and several other prior versions tested, all pages of the PDF document display as expected, even when the initial view contains multiple pages.

What went wrong?
I was not able to provoke the internal viewer to produce debugging output, and I was not able to set js breakpoints in the internal pdf viewer extension to debug the issue, so I am unsure of how to proceed with additional debugging.

Did this work before? Yes 49
