When in a view and using the filter, if it returns two pages of results, you can
go to page 2 but you can't go back to page 1. This only seems to happen if
there's two pages of results - it works fine if there's three or more.

Steps to recreate:
-Go to a view with lots of entries
-Click on Filter and search for something that will yield exactly 2 pages of
results
-Use the dropdown to go to page 2
-Page 1 is now pre-selected in the dropdown, with no way to select it.
