Description

setup fpc.backdropView.dismissalTapGestureRecognizer.isEnabled = true

when fpc in tip state, backdropView don't respond the dismissalTapGesture change state to full, backdropView's dismissalTapGestureRecognizer is work.

Expected behavior

when setup fpc.backdropView.dismissalTapGestureRecognizer.isEnabled = true, whatever current state, tap backdropView to dismiss FloatingPanel

Actual behavior

see desc

    init(_ vc: FloatingPanelController, layout: FloatingPanelLayout, behavior: FloatingPanelBehavior) {
        ownerVC = vc

        surfaceView = SurfaceView()
        surfaceView.position = layout.position
        surfaceView.backgroundColor = .white

        backdropView = BackdropView()
        backdropView.backgroundColor = .black
        backdropView.alpha = 0.0

initial backdropView.alpha = 0.0 will ignore the gesture.

Maybe need replace alpha with UIColor.clearColor

Hi @778477 This is the expected behavior. The dismissal tap is designed to work only when its backdrop view alpha is zero because the backdrop view doesn't appear in UI and user interactions should be passed through the backgound view(main content).
