Ping for review?

LGTM, for some reason it's so much harder to work out what sticky bottom comes
out to vs sticky top.

<div class="group">
nit: It's a bit confusing to work out what's going on in each of these tests,
maybe add comments like:
<!-- .sticky element pushed as far up as possible to table edge. -->

<!-- .sticky element stuck to bottom of .scroller. -->

<!-- .sticky element unstuck. -->
