Odd Pages Left option disabled/enabled at wrong time

Link to original bug (#750613)
Description
The Odd Pages Left option is grayed out when you are not viewing a document in Dual page mode. After switching to Dual, the option is still grayed out until you either change the zoom level or view a new page.
When you switch from Dual to Single page view, the option is still available until you change the zoom level or view a new page.
The option should be available immediately in Dual, and grayed out immediately in Single, or it should always be available, since it doesn't affect anything in Single page view.
