The highlight is an overlay inside the pressable rather than a background on
it, because the node Reanimated animates cannot also carry a themed Unistyles
style. An overlay inherits nothing, so a rounded sidebar row flashed square.
Take the corners from the pressable's own style. The row already declares its
shape once, and a highlight that restated it would be a second copy free to
drift; highlightStyle is left meaning only what the highlight is painted with.
Corners apply before it, so a caller can still depart from the row's shape.
