The PullRefresh plugin, added to a list (modern toolkit) does not work if all of the list's items fit within the display, for example 2-3 items, when swiping down nothing happens.
When the list has more items that can fit on the screen then it works.
That should not be the case since the plugin is for refreshing, and should not depend on how many items the list has.
I suspect some scrolling related issue with list/plugin
