they were sticky at the top, which put them over the first line — and on a
one-line block, which is most of them in a chat, over the whole thing.
absolute bottom-right inside the surface now, with `.code-surface` given the
`position: relative` it never had. that omission is why a control could end up
escaping to the nearest positioned ancestor and floating below the block it
belongs to.
`padding-bottom` on the pre to go with the existing `padding-right`: the last
line is the one they overlap now, and it needs its own room the same way the
first line needed it before.
the trade the old comment was worried about is real but smaller than it reads:
a block taller than the viewport now has its controls at the bottom rather
than the top. that is where you end up after reading it anyway, and it is a
worse place to be only for a block you never scroll — which is exactly the
block whose first line the old position was covering.
