Javascript error in full screen: PDFViewer_setCurrentPageNumber: "X" is out of bounds.

[Burkazoid]

Occurs when viewing any PDF.

Configuration:

• Web browser and its version: Chrome (Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36)
• Operating system and its version: Windows 10
• PDF.js version: Latest (occurs on demo)

Steps to reproduce the problem:

1. Open any pdf file with pdfjs (or go to demo: https://mozilla.github.io/pdf.js/web/viewer.html)
2. Click into full screen / presentation mode.
3. Keep clicking on page to go to the next page. Once you click on the final page, you'll get a javascript error in your console: "PDFViewer_setCurrentPageNumber: "X" is out of bounds" for each click, where X is the number of the last page + 1.

What is the expected behavior?
No javascript error occurring.

What went wrong?
Javascript error: "PDFViewer_setCurrentPageNumber: "X" is out of bounds" for each click.

Thankfully this doesn't break any functionality, just produces an error in the console.

From looking at the code, perhaps this is intentional. Just seems a bit odd to me to produce a console error for standard user behaviour.
