This may not be spot on, as I obviously cannot run your code to try it out (and I am also stuck on a very early version of Apex where it does work), but first you need to give the region in question a static ID (this is done in the region definition).
Then, in Page Rendering --> CSS.
#<static-ID> .uReportDownloadLinks {position:sticky; bottom:-8px; background-color:#cccccc; padding-top:8px; padding-bottom:8px; z-index:999};
You may have to replace .uReportDownloadLinks with what is appropriate for your template. Use Chrome's inspect ability to help you.
If you don't know CSS, suggest you get learning it. Google "css position sticky" for more info.
But it's the
position:sticky; bottom:-8px
bit that's the really important part.
