Stop hiding the type labels whenever the preview is shown

The labels were tied to the preview pill on the grounds that the pill
sat on top of them, but the pill is anchored to the top of the swatches
and the labels to the bottom, so they don't contend for the same space.
Measured at every height from the pill's own minimum (200) upward, the
smallest gap between the two is still around 30pt — so at any size where
the preview appears at all, there was room for both.
