+Whether to `preventDefault()` native events. Native behavior is prevented by
+default. If an anchor is the child of `Press`, internal and external navigation
+should be performed in `onPress`/`onLongPress`. To rely on native behavior
+instead, set `preventDefault` to `false`, but be aware that native behavior will
+take place immediately after interaction without respect for delays or long
+press.
