Table not refreshing pagination changes if done on last page?

jeffw

I have a table with 46 entries. On first page the length selection works fine: if i choose 50 then all rows appear.

If I set it to 10 per page, then go to the last page, I'm seeing the correct entries (rows 41-46). Now, if I select 50 per page, instead of seeing them all, i'm still seeing 41-46. The page numbers redraw but the table itself doesn't.

Has anyone else seen this/fixed it? I'm not assigning any events to the pagination drop down.
