When I open a document in 'Facing Pages', or 'Overview' mode with 2 columns, with the zoom set to 'Fit Width', pressing the 'Page Down' or down arrow buttons on the keyboard doesn't allow you to get past page 2. The page counter just flips between 1 and 2 each time you scroll down to the next page. Pressing 'Go->Next Page' or the green arrow next to the page counter does allow you to get to the next 2 pages, from then on behaviour is normal, skipping to the next pair of pages (3->5->7...). When I scroll back up, I'm stuck again in the 1-2 loop. This behaviour does not appear when the document is shown in 'View->Fit Page' mode. 

Reproducible: Always

Steps to Reproduce:
Open file
View->View Mode->Facing Pages
View->Fit Width on
Press PgUp/downarrow

Actual Results:  
Pages shown are 1&2, counter loops between 1 and 2

Expected Results:  
Pages shown are 3&4, counter changes from 1 to 3
