Steps to reproduce the problem:
http://linux-training.be/linuxfun.pdf
Click on any page number
Try to go back to the previous position via ALT+LEFT
Observe Chrome actually goes back to the page before the PDF and not the previous position in the PDF

What is the expected behavior?
I would like to go back to the previous position like I can in Adobe Reader.

What went wrong?
Sometimes I am reading a PDF in Chrome and it has a page number and I click the page number and it takes me to the page. Then I decide I want to go back to where I was. In adobe reader this would be easy, but in Chrome it isn't. Clicking back does not go back to the previous position.

Did this work before? No
