Pressable's click handler calls stopPropagation, so the bubble-phase
preventDefault on the wrapping <a> never fired and the Electron view
navigated to the href in addition to the existing helper opening it
in the OS browser. Move preventDefault to onClickCapture (and
onAuxClickCapture for middle-click) so it always runs first. The
existing Pressable.onPress helper remains the only path that actually
opens links.
