Mobile product list changes between one product per "line" and two products per line

[tswfi]

open a category page, defaults to two products side by side

use pager to go one page forward and one page back (ajax query replaces content). Now it is one product per page

and if you got to page 3 with the paging buttons, you will see one product per line. but if you reload the page completely it will again be two products side by side.

productClasses are defined differently on full page load and ajax content

Now which one is "correct" is a great question :D

Correct is two columns ;-)
