Florian Müllner e43c8f6364 st: Delay handling of :first/:last-child changes
Updating the :first/:last-child pseudo classes can result in a lot
of unnecessary style changes when bulk-adding children to a container,
as every child ends up as the new last child.

Address this by deferring the style change to an idle, so we only do
the work once for the actual first and last child.
