Minor Description
When the data grid's previous / next pager renders, it only renders the "previous" and "next" text when those pages exist. This is different than how the first/prevous next/last pager renders. The result is that the text only appears when there is such a page, but this causes the page to "jump" around when scrolling through a data set and is inconsistent.
Ultimately, both words should always render but be a link only when necessary.
